Absence of jet quenching in peripheral nucleus–nucleus collisions

Jet Quenching in Heavy Ion Collisions

Simulation of Jet Quenching in Heavy Ion Collisions

One of the important tools for studying the properties of quark-gluon plasma (QGP) in ultrarelativistic heavy ion collisions is the analysis of a QCD jet production. The medium-induced energy loss of energetic partons, “jet quenching”, should be very different in the cold nuclear matter and QGP, resulting in many observable phenomena . Recent RHIC data on high-pT particle production at √ s = 20...

Fast simulation of jet quenching in ultrarelativistic heavy ion collisions

The method for simulation of medium-induced rescattering and energy loss of hard partons in ultrarelativistic heavy ion collisions is developed. The model is realized as fast Monte-Carlo tool implemented to modify standard PYTHIA jet event.

Phenomenology of Jet Quenching in Heavy Ion Collisions

It is commonly believed that the yield for “hard” observables in high-energy nuclear reactions scales as the number of binary nucleon-nucleon (NN) collisions occurring during the encounter of the two nuclei. This expectation applies to processes that are characterized by a high virtuality q, for which final state interactions are negligible, such as lepton pair production or the total yield of ...

K/π Probes of Jet Quenching in AA Collisions

Non-abelian energy loss in quark gluon plasma is shown to lead to novel hadron ratio suppression patterns in ultrarelativistic nuclear collisions. We apply recent (GLV) estimates for the gluon radiative energy loss, which increases linearly with the jet energy up to E < 20 GeV and depends quadratically on the nuclear radius, R. The K/π ratio is found to be most sensitive to the initial density ...
