Jet quenching as a probe of gluon plasma formation
We study, in a pQCD calculation augmented by nuclear effects, the jet energy loss needed to reproduce the π spectra in Au+Au collisions at large pT , measured by PHENIX at RHIC. The transverse width of the parton momentum distributions (intrinsic kT ) is used phenomenologically to obtain a reliable baseline pp result. Jet quenching is applied to the nuclear spectra (including shadowing and mult...
متن کاملJet quenching via jet collimation
The strong modifications of dijet properties in heavy ion collisions measured by ATLAS and CMS provide important constraints on the dynamical mechanisms underlying jet quenching. In this work, we show that the transport of soft gluons away from the jet cone — jet collimation — can account for the observed dijet asymmetry with values of q̂ L that lie in the expected order of magnitude. Further, w...
متن کاملJet Quenching
High-pt particles produced in nucleus-nucleus collisions constitute a powerful tool to study the medium properties. The energy loss resulting from the propagation of these particles in the produced medium translates into a suppression of the high-pt yields. These effects are usually associated to medium-induced gluon radiation which, in turn, predicts a broadening of the jet-like signals. Both ...
متن کاملLattice study of the jet quenching parameter.
We present a first-principle computation of the jet quenching parameter, which describes the momentum broadening of a high-energy parton moving through the deconfined state of QCD matter at high temperature. Following an idea originally proposed by Caron-Huot, we explain how one can evaluate the soft contribution to the collision kernel characterizing this real-time phenomenon, analyzing certai...
