I will discuss the present status and prospects for future developments and applications of the (soon publicly available) JEWEL code. JEWEL is a fully microscopic Monte Carlo event generator for jet evolution in a dense, strongly interacting medium. It employs a consistent perturbative approach using a common framework for all scattering and radiation processes. This construction allows for...

We present measurements of the jet fragmentation functions and transverse momentum profiles (shapes) in PbPb collisions at 2.76 TeV per nucleon-pair center of mass energy with the CMS detector. Jets are reconstructed by the anti-kT sequential clustering algorithm with a resolution parameter of 0.3, using particle-flow objects that combine tracking and calorimetric information. In this talk the...

We study the evolution of a high energy jet triggered by its interactions with a dense QCD medium. We show that the relatively components of the jet which propagate at large angles can be described as the products of a classical branching process, in which successive branchings proceed independently from each other. This exploits the fact that the in-medium rescattering is very efficient in...

A Linearized Boltzmann Transport model is developed for the study of parton propagation inside quark-gluon plasma. Both leading partons and thermal recoiled partons are tracked so that one can also study jet-induced medium excitation. In this study, we implement the complete set of elastic parton scattering processes and investigate elastic parton energy loss, transverse momentum broadening...

We study the modification of jet properties in a heavy ion environement by the presence of strongly coupled quark gluon plasma. We explore a hybrid approach, in which the high virtuality splitting processes that dominate the QCD shower proceed as in vacuum while the partons of the shower interact with the system as dictated by strongly coupled computations via the AdS/CFT correspondence. We...

The ALICE collaboration at the LHC presents a measurement of jet production rates recoiling back-to-back from a high pT trigger hadron. The observable is the difference between normalized recoil jet spectra for two hadron pT trigger intervals. This approach allows the removal of the large combinatorial jet background in heavy ion events in a model-independent way, while preserving collinear...

Jets are collimated QCD multi-particle states that are abundantly produced in heavy-ion collisions at the LHC. Their description in the vacuum is governed by hardest scale of the problem, typically the jet virtuality. In the presence 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 interactions. It was...

Initial State and Proton-Nucleus Collision Phenomena
Oral
In this work we investigate how the energy and momentum lost by partonic jets in the 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, which are solved on an event by event basis. We find that the average integrated elliptic...

Measurements of reconstructed jets in high-energy proton-lead collisions over a wide rapidity and pT range can shed light on the partonic structure of nuclei. Inclusive jet production is sensitive to the nuclear modification of parton distribution functions and, in the forward direction and at small transverse momenta, can provide constraints on the saturation of low Bjorken-x partons in the...
