Jets reconstruction possibility in pAu and AuAu interactions at STAR RHIC

We consider the possibility of jet extraction in the acceptances of the STAR RHIC detector, -2 < η < 2, for an energy of √s = 200 GeV per nucleon in the pAu and AuAu modes at RHIC. 100 events of pAu and AuAu interactions simulated with the FRITIOF code have been used in this study. For AuAu interactions, we also consider separately the case of central interactions with the impact parameter b < rAu = 6.7 fm and more than 4000 particles in the acceptances of the STAR detector. To study the jet shape at √s = 200 and 500 GeV, we have used the PYTHIA simulation code for the direct photon and jet production mode pp → γ + jet and data from the CDF and D0 collaborations. We have found that taking into account the jet shape information improves jet findings and reconstruction possibility significantly, i.e., by one-two orders of magnitude greater
