This construction allows for the co nsistent treatment of recoils\, radiation off recoiling scattering centres \, multiple gluon emission\, interplay between vacuum and medium induced r adiation and interferences. At the same time it is very constrained leavin g little room for tuning and allowing for a quantitative assessment of unc ertainties related to the basic assumptions. Despite its being based on fe w minimal assumptions JEWEL results are in reasonable agreement with exper imental data for both jets and leading hadrons.

The ATLAS experiment at the LHC uses the proton and heavy ion collisions produced in this 27 km l ong collider to probe the predictions and limitations of the Standard Mode l. Due to the high energies employed\, collisions are able to probe a regi me known as the Colour Glass Condensate (CGC): a medium characterized by a part of the hadronic wavefunctions being dominated by nonperturbatively l arge gluon occupation numbers. The JIMWLK equation is a mathematical tool used to predict some of the physical observables within the CGC framework. By exploiting appropriate exclusive interactions (where at least one of t he protons does not break)\, this work attempts to calculate the exclusive J/Psi production cross-section using a truncation of the JIMWLK equation and to measure this cross-section in the ATLAS experiment.\n\nhttps://indi co.tlabs.ac.za/event/30/contributions/300/ LOCATION:Stellenbosch Institute for Advanced Study Garden Route URL:https://indico.tlabs.ac.za/event/30/contributions/300/ END:VEVENT BEGIN:VEVENT SUMMARY:Elliptic Flow from Non-equilibrium Initial Condition with a Satura tion Scale DTSTART;VALUE=DATE-TIME:20131107T140000Z DTEND;VALUE=DATE-TIME:20131107T142000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-302@indico.tlabs.ac.za DESCRIPTION:Speakers: Francesco Scardina (University of Catania (INFN-LNS) )\nA current goal of relativistic heavy ion collisions experiments is the search for a Color Glass Condensate (CGC) as the limiting state of QCD mat ter at very high density.

At RHIC energy we find the available data on v2 are in agreement with a 4πη/s ∼ 1 also for KLN initial conditions.

We apply such DPS formalism to two different final-states at CERN LHC energies: (i) same-sign W-boson pair production i n p-Pb [1]\, and (ii) double-J/psi production in Pb-Pb [2]\, using NLO pre dictions with nuclear PDF modifications for the corresponding single-parto n scatterings. The first process can help determine the effective sigma_ef f parameter characterising the transverse distribution of partons in the n ucleon. The second process provides interesting insights on the event-by-e vent enhancements and/or suppressions observed in prompt-J/psi production in Pb-Pb collisions at the LHC.

It has been claimed to provide good descriptio ns of differential production cross sections of several quarkonia\, while failing to reproduce the polarization measurements\, a problem often attri buted to the unreliability of the measurements. In this presentation we sh ow how the very recent LHC measurements\, both cross sections and polariza tions\, compare to NRQCD. We show that different NLO NRQCD approaches lead to seemingly contradictory conclusions and we offer some thoughts regardi ng what this surprising observation tells about the validity of the NRQCD framework and about quarkonium production. In particular\, we explore the possibility that the long-distance matrix elements (LDMEs) describing the transitions from the colour octet states to the observable states\, crucia l non-perturbative ingredients of the calculations\, might not be universa l. In that case\, the NRQCD framework remains valid\, but hadroproduction and photoproduction data are not described by the same set of matrix eleme nts. This observation\, while not being as surprising as one might tend to think at first\, triggers intriguing questions on the importance of the s urrounding hadronic environment in the production of quarkonium states\, a lready in elementary collisions.\nThis discussion shows that it is not unr easonable to expect different LDMEs in pp and PbPb collisions\, where the abundance of gluons may favour otherwise suppressed transitions. Studies o f quarkonium production in heavy-ion collisions\, to probe QGP melting and /or recombination effects\, are therefore remarkably intertwined with the ("cold") nuclear modifications of the LDMEs. We conjecture that accurate r esults on J/psi and Upsilon(1S) polarizations in Pb-Pb collisions\, easily obtainable at the LHC\, could provide unique measurements of the long-sou ght P-wave suppression patterns\, thereby reliably probing sequential quar konium melting\, a signature of deconfinement mostly insensitive to "cold nuclear matter" effects.\nWe finish by proposing measurements of the polar izations of quarkonia in ultra-peripheral Pb-Pb collisions\, as a way to s tudy quarkonium production in still another environment\, dominated by gam ma-gamma interactions instead of gluon-gluon interactions. Such data could provide a clear-cut challenge to LDME universality.\n\nhttps://indico.tla bs.ac.za/event/30/contributions/309/ LOCATION:Stellenbosch Institute for Advanced Study Garden Route URL:https://indico.tlabs.ac.za/event/30/contributions/309/ END:VEVENT BEGIN:VEVENT SUMMARY:Jet measurements from the CMS Collaboration DTSTART;VALUE=DATE-TIME:20131105T090000Z DTEND;VALUE=DATE-TIME:20131105T093000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-324@indico.tlabs.ac.za DESCRIPTION:Speakers: Yue Shi Lai (Massachusetts Institute of Technology)\ nhttps://indico.tlabs.ac.za/event/30/contributions/324/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain & Good H ope URL:https://indico.tlabs.ac.za/event/30/contributions/324/ END:VEVENT BEGIN:VEVENT SUMMARY:Measurement of jet structure in Pb+Pb collisions using the ATLAS d etector DTSTART;VALUE=DATE-TIME:20131105T093000Z DTEND;VALUE=DATE-TIME:20131105T100000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-325@indico.tlabs.ac.za DESCRIPTION:Speakers: Aaron Angerami (Columbia University)\nhttps://indico .tlabs.ac.za/event/30/contributions/325/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain & Good H ope URL:https://indico.tlabs.ac.za/event/30/contributions/325/ END:VEVENT BEGIN:VEVENT SUMMARY:Light and heavy flavor energy loss phenomenology DTSTART;VALUE=DATE-TIME:20131106T063000Z DTEND;VALUE=DATE-TIME:20131106T070000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-326@indico.tlabs.ac.za DESCRIPTION:Speakers: Magdalena Djordjevic (Institute of Physics\, Univers ity of Belgrade)\nhttps://indico.tlabs.ac.za/event/30/contributions/326/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain & Good H ope URL:https://indico.tlabs.ac.za/event/30/contributions/326/ END:VEVENT BEGIN:VEVENT SUMMARY:ALICE results on the production of light-flavor hadrons at the LHC DTSTART;VALUE=DATE-TIME:20131105T100000Z DTEND;VALUE=DATE-TIME:20131105T103000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-327@indico.tlabs.ac.za DESCRIPTION:Speakers: Jacek Otwinowski (GSI Helmholtz Centre for Heavy Ion Research)\nhttps://indico.tlabs.ac.za/event/30/contributions/327/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain & Good H ope URL:https://indico.tlabs.ac.za/event/30/contributions/327/ END:VEVENT BEGIN:VEVENT SUMMARY:Centrality dependence of charged particle spectra in Proton-Lead c ollisions at sort(s_NN) = 5.02 TeV with the ATLAS detector DTSTART;VALUE=DATE-TIME:20131107T115000Z DTEND;VALUE=DATE-TIME:20131107T121000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-328@indico.tlabs.ac.za DESCRIPTION:Speakers: Martin Spousta (Charles University in Prague)\nTo Be Completed\n\nhttps://indico.tlabs.ac.za/event/30/contributions/328/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain URL:https://indico.tlabs.ac.za/event/30/contributions/328/ END:VEVENT BEGIN:VEVENT SUMMARY:Quarkonium production and polarization in pp collisions with the C MS detector DTSTART;VALUE=DATE-TIME:20131107T134000Z DTEND;VALUE=DATE-TIME:20131107T140000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-312@indico.tlabs.ac.za DESCRIPTION:Speakers: Valentin Knuenz (Institute of High Energy Physics\, Vienna\, Austria)\nStudies of the production of heavy quarkonium states ar e very important to improve our understanding of QCD and hadron formation\ , given that the heavy quark masses allow the application of theoretical t ools less sensitive to nonperturbative effects.\n\nThanks to a dedicated d imuon trigger strategy\, combined with the record-level energy and luminos ity provided by the LHC\, the CMS experiment could collect large samples o f pp collisions at 7 and 8 TeV\, including quarkonium states decaying in t he dimuon channel. This allowed the CMS collaboration to perform a series of systematic measurements in quarkonium production physics\, including do uble-differential cross sections and polarizations\, as a function of rapi dity and pT\, for five S-wave quarkonia: J/psi\, psi(2S)\, Y(1S)\, Y(2S)\, and Y(3S). Some of these measurements extend well above pT~50 GeV\, probi ng regions of very high pT/mass\, where the theory calculations are suppos ed to be the most reliable. Thanks to its high-granularity silicon tracker \, CMS can reconstruct low-energy photons through their conversions to e+e - pairs\, thereby accessing the radiative decays of the P-wave quarkonium states\, with an extremely good mass resolution\, so that the J=1 and J=2 1P states can be resolved. This allows CMS to determine cross-section rati os and feed-down decay fractions involving the chi states\, in both the ch armonium and bottomonium families. Such measurements provide crucial input s to a better understanding of quarkonium production as a signal of new ph ysics in Pb-Pb collisions.\n\nThis talk presents the CMS quarkonium produc tion results\, in pp collisions\, placing emphasis on the most recent meas urements\, which include the polarizations of all five S-wave states\, the most comprehensive measurement of quarkonium polarization made so far. We will also present brand-new results on P-wave quarkonium production in th e bottomonium family. It is likely that other preliminary results on quark onium production in pp collisions\, of particular relevance for the unders tanding of heavy-ion measurements\, will be shown at this conference for t he first time.\n\nhttps://indico.tlabs.ac.za/event/30/contributions/312/ LOCATION:Stellenbosch Institute for Advanced Study Garden Route URL:https://indico.tlabs.ac.za/event/30/contributions/312/ END:VEVENT BEGIN:VEVENT SUMMARY:Radiation spectrum of a massive quark-gluon antenna in a QCD mediu m DTSTART;VALUE=DATE-TIME:20131105T131000Z DTEND;VALUE=DATE-TIME:20131105T133000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-313@indico.tlabs.ac.za DESCRIPTION:Speakers: Manoel Rodríguez Calvo (Universidade de Santiago de Compostela - IPhT CEA Saclay)\nWe derive the radiation spectrum of a mass ive quark-gluon antenna in a QCD medium.

We argue that the transverse flow has a rapidity- even component that is similar to collective flow in a fluid and emerges f rom the QCD analog of Farady's and Ampere's Law\, and it has a rapidity-od d component that can be understood from Gauss' Law for gluon fields. While the former leads to the usual radial and elliptic flow phenomena\, the ra pidity-odd flow term implies directed flow and leads to characteristic flo w patterns in asymmetric systems like Cu+Au. A comprehensive study of thes e unique flow phenomena could lead to novel signatures of color glass. We also discuss a method to calculate initial conditions for a further viscou s hydrodynamic evolution from the full energy momentum tensor of the gluon field. This allows us to calculate the phenomenological consequences of t he initial gluon field flow.

Their interaction with QCD medium is sensitive to the medium dynami cs. Thus heavy flavor quarks are suggested as an ideal probe to study the properties of the hot and dense nuclear matter created at RHIC. In this ta lk\, we will present recent open heavy flavor measurements by the STAR exp eriment through both hadronic and semi-leptonic decay channels. We will\nd iscuss results of open charm meson and non-photonic electron production cr oss section measurements in proton-proton and Au+Au collisions at $sqrt{s_ NN}$ = 200 GeV. We will also present measurements of open charm mesons in proton-proton collisions at $sqrt{s}$ = 500 GeV and the first result in u ranium-uranium collisions at $sqrt{s_{NN}=193$ GeV.

Both show unexpected features. The J/psi mod ification at forward rapidity requires a stronger than linear dependence o f suppression on nuclear thickness\, while the psi' suppression for centra l collisions is unexpectedly stronger than that for the J/psi. There will be a discussion of the implications of the rapidity dependence and of the centrality dependence\, and also of why we believe that the centrality mea surement is reliable. \n\nIt has long been assumed that that p(d)+A data p rovide the baseline for measuring hot nuclear matter effects in A+A collis ions by isolating the "cold nuclear matter" effects. However recent result s from p+Pb at the LHC and d+Au at RHIC show correlations of soft particle s across large rapidity gaps that are consistent with flow.

Their description in the vacuum is governed b y hardest scale of the problem\, typically the jet virtuality. In the pres ence of a background color field\, e.g. such as expected in a quark-gluon plasma\, one also has to consider a hard scale arising from the medium int eractions. It was recently shown that due to the collinear nature of QCD s plittings\, high-energy jets are typically quite collimated and are not re solved by the medium\, i.e. they are only seen as a total charge and lose energy coherently. Assuming this scenario holds for all jets\, we show how a factorization of small-angle jet evolution and large-angle medium-induc ed emissions can be realized and calculate three key observables: the jet RAA\, modification of the intra-jet structure and the amount of out-of-con e radiation. Medium-induced radiation is accounted for using the establish ed factorization of multiple branchings leading to the probabilistic rate equation - which we presently improve upon by introducing finite-size eff ects and a proper regularization prescription in the infrared. This mechan ism is particularly important for the transport of energy away from the je t axis up to large angles. For the intra-jet structure\, on the other hand \, we find the striking importance of so-called "antiangular ordered radia tion\," resulting from the slight decoherence of the jet during the passag e through the medium.\n\nhttps://indico.tlabs.ac.za/event/30/contributions /349/ LOCATION:Stellenbosch Institute for Advanced Study Good Hope URL:https://indico.tlabs.ac.za/event/30/contributions/349/ END:VEVENT BEGIN:VEVENT SUMMARY:The parton cascade BAMPS with the improved Gunion-Bertsch matrix e lement DTSTART;VALUE=DATE-TIME:20131104T152000Z DTEND;VALUE=DATE-TIME:20131104T154000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-350@indico.tlabs.ac.za DESCRIPTION:Speakers: Carsten Greiner (Goethe University Frankfurt)\nAn up dated version of the partonic transport model Boltzmann Approach to MultiP arton Scatterings (BAMPS) is presented\, which allows interactions among a ll partons: gluons\, light quarks\, and heavy quarks with elastic and inel astic collisions.

Produced in hard scattering processes in the initial stages of the collision\, they i nteract with the medium\, lose energy and\, depending on the coupling stre ngth to the medium\, take part in the collective motion of the QGP matter. ALICE measured the production of D0\, D*+\, D+ and Ds mesons at central rapidity in pp\, p-Pb and Pb-Pb collisions at the LHC. The study of the mo dification of the transverse-momentum differential yields of charm particl es in Pb-Pb collisions with respect to pp collisions\, quantified by the n uclear modification factor (RAA)\, can unravel details of the energy loss mechanism\, such as its dependence on the quark mass and on the path lengt h the parton travels through the medium. A similar comparison between pp a nd p-Pb collision data (RpPb) is fundamental to disentangle effects relate d to the presence of the hot medium from cold nuclear matter effects\, amo ng which nuclear shadowing\, suppressing the gluon PDF at low Bjorken-x\, is the most important for charm at LHC energies. The degree of thermaliza tion and coupling to the medium is investigated in semi-peripheral Pb-Pb c ollisions by measuring the elliptic flow coefficient (v2)\, which quantifi es the angular dependence of the particle production with respect to the r eaction plane of the collision and\, at high pT\, is sensitive to the path -length dependence of the energy loss. The latter dependence can be also addressed by studying the modification to the azimuthal correlation distri bution of D mesons and charged hadrons in central Pb-Pb collisions with re spect to pp collisions.\nResults on the transverse momentum and centrality dependence of the D-meson elliptic flow and RAA will be presented. The c omparison with the RAA of non-prompt J/ψ from B decay measured with CMS w ill be discussed. The preliminary results on D-meson RpPb and the dependen ce of D-meson yields on rapidity in p-Pb collisions will be shown.

Within the framework of a La ngevin equation coupled to a (2+1)-dimensional viscous hydrodynamic model\ , we introduce an algorithm that incorporates not only collisional\, but a lso radiative energy loss for heavy quarks by treating the medium-induced gluon radiation as a recoil force term for heavy quarks traversing the QGP matter. The subsequent hadronization process is calculated using a hybrid recombination plus fragmentation model. Within this improved transport fr amework\, our calculation shows significant contributions from gluon radia tion to heavy quark energy loss at high energies\; the recombination mecha nism is found important for heavy flavor meson production at intermediate energies. Our numerical results provide a good description of D meson supp ression and flow measured at both RHIC and LHC\, as well as predictions fo r the future measurements of B mesons. In addition\, a new observable – the angular correlation function of heavy flavor pairs – is explored in our study and found to be a potential candidate for distinguishing differe nt energy loss mechanisms of heavy quarks inside a QGP.\n\nhttps://indico. tlabs.ac.za/event/30/contributions/369/ LOCATION:Stellenbosch Institute for Advanced Study Good Hope URL:https://indico.tlabs.ac.za/event/30/contributions/369/ END:VEVENT BEGIN:VEVENT SUMMARY:Jet Physics Theory DTSTART;VALUE=DATE-TIME:20131105T063000Z DTEND;VALUE=DATE-TIME:20131105T070000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-370@indico.tlabs.ac.za DESCRIPTION:Speakers: Carlos Salgado (Universidade de Santiago de Composte la)\nhttps://indico.tlabs.ac.za/event/30/contributions/370/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain & Good H ope URL:https://indico.tlabs.ac.za/event/30/contributions/370/ END:VEVENT BEGIN:VEVENT SUMMARY:Fully Reconstructed Charged Jets in Central Au+Au Collisions at sq rt(s_NN)=200 GeV from STAR DTSTART;VALUE=DATE-TIME:20131105T070000Z DTEND;VALUE=DATE-TIME:20131105T073000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-371@indico.tlabs.ac.za DESCRIPTION:Speakers: Jan Rusnak (Nuclear Physics Institute\, Academy of S ciences of the Czech Republic)\nhttps://indico.tlabs.ac.za/event/30/contri butions/371/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain & Good H ope URL:https://indico.tlabs.ac.za/event/30/contributions/371/ END:VEVENT BEGIN:VEVENT SUMMARY:STAR: What Have Hard Probes Taught Us about the Quark-Gluon Plasma ?

This is especially interesting in view of our earlier\nresult s that showed that realistic transverse expansion of the bulk\nmedium redu ces high-pT elliptic flow from GLV energy loss by nearly half\ncompared to transversely frozen evolution scenarios.\n\nhttps://indico.tlabs.ac.za/ev ent/30/contributions/380/ LOCATION:Stellenbosch Institute for Advanced Study Good Hope URL:https://indico.tlabs.ac.za/event/30/contributions/380/ END:VEVENT BEGIN:VEVENT SUMMARY:Johnnie Thews DTSTART;VALUE=DATE-TIME:20131105T165000Z DTEND;VALUE=DATE-TIME:20131105T170000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-381@indico.tlabs.ac.za DESCRIPTION:https://indico.tlabs.ac.za/event/30/contributions/381/ LOCATION:Stellenbosch Institute for Advanced Study URL:https://indico.tlabs.ac.za/event/30/contributions/381/ END:VEVENT BEGIN:VEVENT SUMMARY:Bob\, Vesa and Hard Probes DTSTART;VALUE=DATE-TIME:20131105T164000Z DTEND;VALUE=DATE-TIME:20131105T165000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-382@indico.tlabs.ac.za DESCRIPTION:Speakers: Xin-Nian Wang (Lawrence Berkeley National Laboratory )\nhttps://indico.tlabs.ac.za/event/30/contributions/382/ LOCATION:Stellenbosch Institute for Advanced Study URL:https://indico.tlabs.ac.za/event/30/contributions/382/ END:VEVENT BEGIN:VEVENT SUMMARY:Robert Thews DTSTART;VALUE=DATE-TIME:20131105T163000Z DTEND;VALUE=DATE-TIME:20131105T164000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-383@indico.tlabs.ac.za DESCRIPTION:Speakers: Jean Cleymans (University of Cape Town)\nhttps://ind ico.tlabs.ac.za/event/30/contributions/383/ LOCATION:Stellenbosch Institute for Advanced Study URL:https://indico.tlabs.ac.za/event/30/contributions/383/ END:VEVENT BEGIN:VEVENT SUMMARY:Vesa Ruuskanen DTSTART;VALUE=DATE-TIME:20131105T162000Z DTEND;VALUE=DATE-TIME:20131105T163000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-384@indico.tlabs.ac.za DESCRIPTION:Speakers: Ramona Vogt (LLNL and UC Davis\, USA)\nhttps://indic o.tlabs.ac.za/event/30/contributions/384/ LOCATION:Stellenbosch Institute for Advanced Study URL:https://indico.tlabs.ac.za/event/30/contributions/384/ END:VEVENT BEGIN:VEVENT SUMMARY:Video Presentation DTSTART;VALUE=DATE-TIME:20131105T160000Z DTEND;VALUE=DATE-TIME:20131105T162000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-385@indico.tlabs.ac.za DESCRIPTION:Speakers: Helmut Satz (University of Bielefeld\, Germany)\nhtt ps://indico.tlabs.ac.za/event/30/contributions/385/ LOCATION:Stellenbosch Institute for Advanced Study URL:https://indico.tlabs.ac.za/event/30/contributions/385/ END:VEVENT BEGIN:VEVENT SUMMARY:Anisotropic flow of thermal photons as a quark-gluon plasma viscom eter DTSTART;VALUE=DATE-TIME:20131104T152000Z DTEND;VALUE=DATE-TIME:20131104T154000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-387@indico.tlabs.ac.za DESCRIPTION:Speakers: Chun Shen (The Ohio State University)\nAs is well kn own\, photons are a penetrating probe of the dense medium created in heavy -ion collisions. I will present state-of-the-art calculations of viscous p hoton emission from nuclear collisions at RHIC and LHC. Fluctuating initia l density profiles are evolved with event-by-event viscous hydrodynamics. Momentum spectra of thermal photons radiated by these explosively expandin g fireballs and their $p_T$-differential anisotropic flow coefficients $v_ n(p_T)$ are computed\, both with and without accounting for viscous correc tions to the standard thermal emission rates at leading logarithmic order. Viscous corrections to the rates are found to have a larger effect on the $v_n$ coefficients than the viscous suppression of hydrodynamic flow anis otropies. Since photons are found to be more sensitive to the quark-gluon plasma (QGP) shear viscosity than hadrons\, their anisotropic flow coeffic ients $v_n$ serve as a sensitive QGP viscometer.\n\nhttps://indico.tlabs.a c.za/event/30/contributions/387/ LOCATION:Stellenbosch Institute for Advanced Study Garden Route URL:https://indico.tlabs.ac.za/event/30/contributions/387/ END:VEVENT BEGIN:VEVENT SUMMARY:Spatially dependent nPDFs and their applications in inclusive pion and prompt photon production DTSTART;VALUE=DATE-TIME:20131107T125000Z DTEND;VALUE=DATE-TIME:20131107T131000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-389@indico.tlabs.ac.za DESCRIPTION:Speakers: Ilkka Helenius (University of Jyväskylä)\nI will f ocus on the nuclear PDFs (nPDFs) and their applications in high energy A+A and p/d+A collisions.

The small- x region\, however\, is of great interest. The nucleon structure in this region is dominated by gluons which show a rapid rise with decreasing x. At low-x\, this growth must be tamed and the gluon distribution will be sa turated. This saturation phenomena is expected to be universal\, appearin g in both nucleons and nuclei. A knowledge of this regime is of vital imp ortance to understanding the underlying physics which governs the initial conditions of heavy-ion collisions at both the LHC and RHIC\, where partic le production is dominated by gluons from this unknown region.\n\nHowever\ , only tantalising hints of this have been observed so far. Therefore\, t he construction of an Electron-Ion Collider (EIC)\, colliding polarised el ectrons with polarised protons and also a wide variety of nuclei\, will al low an exploration of the region of small-x in great detail (with luminosi ties 100x that of HERA)\, answering questions on both the spatial and mome ntum distributions of gluons and sea quarks in nuclei. In particular\, th e saturation region is more accessible in nuclei due to the amplification of the saturation scale with nuclear size (Q_s ~ A^(1/3)).\n\nIn this talk I will present the current status of the physics capabilities of e+A coll isions at an EIC as outlined in the EIC White paper [1].\n\n[1] A.

These predictions permit an experim ental determination of the dominant physical processes for low-x gluons in a high-energy nucleus. At eRHIC energies\, J/psi photoproduction in e+A c ollisions provides an ideal experimental probe for the spatial distributio n of gluons. EVMP grants experimental access to the edge region of the hig hly-boosted nuclear wavefunction\, where the saturation scale for CGC calc ulations becomes inaccessible to pQCD. On the other hand\, DGLAP evolution requires careful consideration of unitarity effects.\n\nUnder these diffe rent small-x frameworks we obtain a measurable distinction in both the sha pe and normalization of the differential cross section predictions.

this w ork we investigate how the energy and momentum lost by partonic jets in th e quark-gluon plasma may affect the final elliptic and triangular flow of low p_T hadrons at RHIC energies. The jets are modeled as external sources in the energy-momentum conservation equations of ideal hydrodynamics\, wh ich are solved on an event by event basis. We find that the average integr ated elliptic (triangular) flow and the participant eccentricity (triangul arity) can become significantly less linearly correlated if the energy los s rate is sufficiently large (dE/dx > 10 GeV/fm). We show that the linear correlation between v_3(p_T < 1 GeV) and v_3(2 < p_T < 3 GeV) is particula rly sensitive to the magnitude of dE/dx and\, thus\, this new observable m ay be used to distinguish between strong and weak coupling scenarios for t he jet energy loss in the QGP.\n\nhttps://indico.tlabs.ac.za/event/30/cont ributions/412/ LOCATION:Stellenbosch Institute for Advanced Study Good Hope URL:https://indico.tlabs.ac.za/event/30/contributions/412/ END:VEVENT BEGIN:VEVENT SUMMARY:Bottomonium production in pp\, pPb\, and PbPb collisions with CMS DTSTART;VALUE=DATE-TIME:20131104T144000Z DTEND;VALUE=DATE-TIME:20131104T150000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-413@indico.tlabs.ac.za DESCRIPTION:Speakers: Dong Ho Moon (University of Illinois at Chicago)\nTh e three Y states (1S\, 2S\, 3S) were measured separately using the Compact Muon Solenoid (CMS) experimental apparatus via their dimuon decays in pp and pPb collisions\, in the rapidity range |y|<1.9 in the centre-of-mass o f the collision.

Electroweak boson production is an important benchmark process at hadron colliders. Pr ecise measurements of W and Z production in heavy-ion collisions can help to constrain nuclear PDFs as well as serve as a standard candle of the ini tial state in PbPb collisions at the LHC energies. The inclusive and diffe rential measurements of the Z boson yield in the muon decay channel will b e presented\, establishing that no modification is observed with respect t o next-to-leading order pQCD calculations\, scaled by the number of incohe rent nucleon-nucleon collisions. Measurements of the yield of W bosons dec aying into a muon and an (anti)neutrino as a function of centrality\, and the W charge asymmetry as a function of rapidity show no modifications bey ond the expected effect of isospin when compared to pp collisions and the status of the corresponding analyses on pPb collisions will be given.\n\nh ttps://indico.tlabs.ac.za/event/30/contributions/414/ LOCATION:Stellenbosch Institute for Advanced Study Good Hope URL:https://indico.tlabs.ac.za/event/30/contributions/414/ END:VEVENT BEGIN:VEVENT SUMMARY:Transverse momentum and pseudorapidity dependence of charged parti cle production and nuclear modification factor in pPb collisions at sqrt(s NN)=5.02 TeV with CMS DTSTART;VALUE=DATE-TIME:20131104T142000Z DTEND;VALUE=DATE-TIME:20131104T144000Z DTSTAMP;VALUE=DATE-TIME:20260309T023229Z UID:indico-contribution-30-415@indico.tlabs.ac.za DESCRIPTION:Speakers: Krisztian Krajczar (CERN)\nThe charged particle tran sverse momentum (pT) spectra at midrapidity and forward pseudorapidity ran ges up to pT=100 GeV/c are presented for pPb collisions at sqrt(sNN)=5.02 TeV.

Jets are reconstructed by the anti-kT sequen tial clustering algorithm with a resolution parameter of 0.3\, using parti cle-flow objects that combine tracking and calorimetric information. In th is talk the jet properties of inclusive jets with transverse momentum pT > 100 GeV/c in PbPb collisions are measured for reconstructed charged parti cles with pT > 1 GeV/c in a cone of radius sqrt((Δ φ)^2 + ( Δ η)^2)=0. 3 around the jet axis. A data sample of PbPb collisions collected in 2011 at a center-of-mass energy of sqrt{sNN}= 2.76 TeV corresponding to an inte grated luminosity of 150 µb^-1 is used. The results for PbPb collisions a s a function of collision centrality are compared to reference distributio ns based on the full 2013 pp statistics collected at the same collision en ergy. Centrality-dependent modifications of the fragmentation functions an d shapes are revealed.\n\nhttps://indico.tlabs.ac.za/event/30/contribution s/417/ LOCATION:Stellenbosch Institute for Advanced Study Table Mountain URL:https://indico.tlabs.ac.za/event/30/contributions/417/ END:VEVENT END:VCALENDAR
