Parallel Session III: Jet MC and Jet Modification in A+A
- Joern Putschke (Yale University)
Building upon the hybrid strong/weak coupling model for jet quenching, we incorporate the effects of transverse momentum broadening and contributions from the response of the plasma to the jet, aka the wake, and study their effects on a variety of observables. We find little sensitivity to the strength of broadening for inclusive observables. However, we propose new observables constructed...
The highly increased quality and statistics of the experimental data on jet production in heavy-ion collisions, collected in recent years at RHIC and LHC, allow investigation well beyond that of jet suppression in terms of the nuclear modification factor. Of particular interest are multi-particle correlation observables that probe medium-induced modifications either in the trigger-recoil...
Several reconstructed-jet observables are simulated for Pb+Pb collisions at 2.76 TeV by using a multiphase transport (AMPT) model with a triggered dijet (or photon-jet), which provides a complete understanding of the dynamical evolution from jet energy loss in QGP, jet hadronization to jet transport in a hadronic matter. We find that the measured asymmetry of dijet is driven by both initial...
JEWEL is a fully dynamical event generator for jet evolution in a dense
QCD medium, which has been validated for multiple jet and jet-like
observables. Jet constituents (partons) undergo collisions with thermal
partons from the medium, leading to both elastic and radiative energy
loss. The recoiling medium scattering centres carry away energy and
momentum from the jet. Keeping track of...
It has been found that the baryon to meson ratio at intermediate transverse momentum ($p_{\rm T}$) is up to a factor two larger in the systems such as Pb-Pb but also p-Pb collisions than that in pp collisions. Particle production at intermediate $p_{\rm T}$ is expected to have contributions from hadronization of the medium as well as from fragmentation of high-momentum partons.
