Measurement of inclusive jet production in Au+Au collisions at root sNN = 200 GeV by the STAR experiment

Popis výsledku v původním jazyce

The STAR Collaboration reports the measurement of inclusive jet production in central (0-10%) and peripheral (60-80%) Au+Au collisions at root sNN = 200 GeV, using both charged-particle and fully-reconstructed jets. Jet reconstruction is carried out using the anti-kT algorithm with resolution parameters R = 0.2, 0.3 and 0.4. Yield suppression of charged-particle jets is observed for central Au+Au collisions relative to both peripheral Au+Au collisions and a vacuum baseline utilizing PYTHIA 6 simulations. The magnitude of the suppression is similar to that measured at the LHC and can be described by theoretical calculations. No evidence of significant medium-induced jet broadening is observed, based on comparison of jet spectra at varying R. The yield suppression, when expressed as the jet transverse momentum shift corresponding to energy loss, is consistent in magnitude with coincidence measurements at RHIC based on direct-photon and hadron triggers. There is an indication of larger energy loss observed at the LHC.
