SM Higgs searches with the ATLAS experiment at the LHC

• Rachid Mazini (Institute of Physics, Academia Sinica Taiwan)

The latest results of the Standard Model Higgs boson search with the ATLAS experiment, in pp collisions data collected in 2011 and 2012 are presented. Individual search channels, as well as their combination are detailed. The significance of the observed excess of the Higgs-like resonance are updated and presented. Preliminary results from the measurement of the properties of the Higgs-like particle are presented.

Search for the Standard Model Higgs at the LHC

• Mayda Velasco (Northwestern University)

Results about the experimental searches for the Standard Model Higgs in the decays to fermions and gauge bosons at a collision energy of 7 and 8 TeV at the LHC are presented. The analysis uses pp collision data recorded by the CMS detector at the LHC, corresponding to integrated luminosities of 5.05 fb-1 at collision energy of 7 TeV and 5.26 fb-1 at 8 TeV. The searches cover overall Higgs boson mass hypotheses in the range 110 < m_H < 600 GeV. A complete description of the analyses for the H->gg and H->ZZ-> 4lepton searches, the most clean and high resolution channels, is provided. The nature of the excess of events observed in those two channels is explained. The general strategy and the final results are shown for the searches of the Higgs boson in the H->WW, H->tautau and H->bb channels. The results for 7 and 8 TeV analyses are combined to derive the best sensitivity of the Higgs searches by the CMS detector at the LHC and the most complete results with 2011 and 2012 data.

Statistics for Higgs search and discovery

• Eilam Gross (Weizmann Institute of Science)

The LHC statistical method is based on the Profile Likelihood test statistics and its asymptotic formalism. In this lecture the statistical methods (including the so called Look Elsehere Effect) and their implications on the Higgs search and discovery at the LHC will be reviewed.

Overview of results from the ALICE Experiment at the CERN LHC

• Yiota Foka (GSI/CERN)

ALICE, designed as a general purpose heavy-ion detector for the CERN Large Hadron Collider has been successfully running for the last three years. Data from pp collisions have been collected at different centre of mass energies, including 0.9, 2.76 and 7 TeV and from Pb-Pb collisions at 2.76 TeV per nucleon. The data analysis shows intriguing properties of the produced matter in Pb-Pb collisions. The results indicate that the created system is larger, hotter and denser compared to the one created in heavy-ion collisions at lower energies and it still behaves like a perfect, strongly interacting liquid. A review of recent ALICE results will be presented.

Strangeness production in the ALICE detector

• Domenico Elia (INFN Bari)

The ALICE experiment at the LHC has measured the production of strange hadrons in Pb--Pb and pp collisions at unprecedented beam energies. Particles are reconstructed via their weak decay topologies exploiting the excellent tracking and particle identification capabilities of the apparatus. Transverse momentum spectra and yields at mid-rapidity have been studied for &Lambda, &Xi^- and &Omega^- baryons and their anti-particles as well as for kaons. Results in Pb--Pb collisions at &radic;s_NN = 2.76 TeV for different centrality intervals will be presented and compared with pp and lower energy nucleus-nucleus measurements.

The African School of Fundamental Physics and its Applications

• Ketevi Assamagan (BNL)

We have established a biennial school of physics in Africa, on fundamental subatomic physics and its applications. The aim of the school is to build capacity to harvest, interpret, and exploit the results of current and future physics experiments with particle accelerators, and to increase proficiency in related applications, such as medicine, and technologies. The school is based on a close interplay between theoretical, experimental, and applied physics. The first school took place in Stellenbosch, South Africa on 1−21 August 2010. We proposed the second edition of the biennial school in Ghana on 15 July – 8 August 2012. In this talk, we will presented the activities of both school in 2010 and 2012.

The charm of hot matter - charmonium and open charm measurements in Pb-Pb collisions with ALICE at the LHC

• Anton Andronic (GSI Darmstadt)

Among the various suggested probes of deconfinement, charmonium states play a distinctive role. J/psi is the first hadron for which a clear mechanism of suppression (melting) in deconfined matter was proposed early on, based on the color analogue of Debye screening. The ALICE measurements of J/psi production in Pb-Pb collisions are performed as a function of collision centrality, transverse momentum and rapidity. The nuclear modification factor of J/psi production shows that, at the LHC, there is an enhanced relative production at low transverse momentum compared to that at lower energies. Corroborated with the measurements of open charm hadrons, which will also be discussed, the charmonium results hint at a production in a thermalized hot medium. Comparisons to model predictions indicate that J/psi production occurs in deconfined matter or at hadronization.

Standard Model and Top Physics with ATLAS

• Killian Rosbach (Université de Genève, DPNC)

The ATLAS collaboration has performed studies of a wide range of Standard Model physics processes in pp collisions. Recent measurements of soft particle to hard photon and jet production, which are sensitive to QCD phenomena, are presented. Drell-Yan, vector boson and diboson production cross sections are also discussed, together with constraints on anomalous triple-gauge boson couplings. Inclusive cross-section measurements for top-quark pair and single top t- and Wt-channels are shown. For top-quark pair production, emphasis is given to differential measurements and additional radiation studies, including also spin correlation and top-quark charge asymmetry. Intrinsic top quark properties as its mass and charge as well as a measurement of the polarization of W bosons in top quark decays are also presented.

Theoretical prediction of ferromagnetic behaviour above room temperature in ZnO (and GaN) doped with dilute concentrations (6 – 8%) of transition metal (TM) ions has excited considerable interest because of their potential as semiconductor-compatible magnetic components for spintronic applications. Observation of room temperature ferromagnetism (RTFM) in ZnO doped with TM ions have been reported, however, no clarity exists on the origin of the observed magnetism, which has been attributed to dopant-defect complexes, unintentional precipitation, or to the formation of secondary magnetic phases. The Mössbauer Collabo-ration at ISOLDE/CERN has applied 57Fe emission Mössbauer spectroscopy following the implantation of 57Mn*, to study the nature of the magnetism in ZnO and other metal oxides and III-nitrides. Radioactive beams of 57Mn+ (T½ = 1.5 min) ions are produced at the ISOLDE facility following fission in a UC2 target induced by 1.4 GeV protons and multi-stage element selective laser ionization. High purity beams of intensity of ~3×108 ions/s were implanted with 40-60 keV energy and to fluences below 1012 ions/cm2 into commercially available single crystal samples. The Mössbauer spectra obtained on-line after implantation into ZnO single crystals show magnetic hyperfine sextets originating from Fe in the high-spin Fe3+ state. Measurements in an external magnetic field show that these sextets are not due to ferromagnetic Fe but to paramagnetic substitutional Fe3+ with unusually long relaxation times. Similar high-spin Fe3+ paramagnetic sextet structure is also observed in MgO and alpha-Al2O3. Results obtained for ZnO, alpha-Al2O3 and MgO, as well as preliminary results for GaN, AlN and InN, will be presented.

Heavy Ion Physics from the CMS Collaboration

• Pradeep Sarin (IIT, Bombay)

The talk presents recent results on collisions involving Pb ions from the CMS Experiment at the LHC. Results include jet quenching and jet modification studies; suppression of the production of J/psi and Y particles and their excited states; electroweak boson production; and global and collective features of heavy ion collisions, such as various distributions and azimuthal asymmetry of the final state charged particles.

Towards the Little Bang Standard Model

• Ulrich Heinz (The Ohio State University)

The Little Bangs created in ultrarelativistic heavy-ion collisions share many characteristic features with the cosmological evolution after the Big Bang. I will demonstrate how quantum fluctuations in the initial state of the Little Bang propagate via hydrodynamic evolution (supplemented by an early pre-equilibrated thermalization and a late kinetic freeze-out stage) into the experimentally observed final state, manifesting themselves as fluctuations in the final flow pattern. A harmonic analysis of the final flows, their transverse momentum dependence and their flow angles (the "Little Bang flow fluctuation spectrum") provides detailed information from which the spectrum of gluon fluctuations in the initial state and the transport coefficients of the quark-gluon plasma fluid created in the collisions can be quantitatively extracted.

Searches for Supersymmetry with the CMS detector at the LHC

We present the results of searches for Supersymmetry performed using the datasets collected in 2011-2012 by the CMS experiment at the LHC in pp-collisions at center-of-mass energy of 7 and 8 TeV. The results are interpreted in the light of the cMSSM and simplified models.
