Quarkonium Production at STAR
range 4 < pT < 12 GeV/c. The pT spectrum and nuclear modification factor for J/ψ with pT < 10 GeV/c is reported, along with results from Υ(1S+2S+3S) production in Au+Au collisions. The nuclear modification factor for high-pT J/ψ (pT > 5 GeV/c) is found to be consistent with unity in peripheral collisions, while a significant suppression of low-pT J/ψ and Υ is observed in central collisions. The...
متن کاملJet Quenching at Rhic
We present high transverse momentum (p T) measurements made at the Relativis-tic Heavy Ion Collider (RHIC) for Au+Au, d+Au, and p+p collisions at √ s N N = 200 GeV, as well as for Au+Au collisions at √ s N N = 62 GeV. We observe a suppression in the yield of high p T hadrons measured in central Au+Au collisions, relative to the yield in p+p collisions scaled by the number of binary nucleon-nucl...
متن کاملO ct 2 00 5 Heavy flavor production in p + p and d + Au collisions at √ s NN = 200 GeV from single leptons over a wide kinematic range
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured single electrons at midrapidity and single muons at forward and backward rapidities (1.2 < |y| < 2.2) for p+p and d+Au collisions at √ s N N = 200 GeV. The inclusive lepton spectra exhibit excesses over light hadron sources. The excesses are attributed to semileptonic decays of charm and bottom hadrons and compared to the...
متن کامل2 00 5 Nuclear modification and elliptic flow measurements for φ mesons at √ s NN = 200 GeV d + Au and Au + Au collisions by PHENIX
We report the first results of the nuclear modification factors and elliptic flow of the φ mesons measured by the PHENIX experiment at RHIC in high luminosity Au+Au collisions at √ sNN = 200 GeV. The nuclear modification factors RAA and RCP of the φ follow the same trend of suppression as π’s in Au+Au collisions. In d+Au collisions at √ sNN = 200 GeV, the φ mesons are not suppressed. The ellipt...
متن کاملNuclear modification factor for identified hadrons at forward rapidity in Au + Au reactions at 200 GeV
Herewith we present the production of identified hadrons in Au + Au and p + p collisions at √ s N N = 200 GeV at forward rapidity, y ≈ 3.2. Suppression of pions and kaons and enhancement for protons in central Au + Au collisions is observed. These results are found to be very similar in strength to that observed at mid-rapidity. Furthermore, we see a gradual decrease of the observed suppression...
