Title: Probing properties of hot and dense QCD matter with heavy flavor in the PHENIX experiment at RHIC

Abstract

Hadrons carrying heavy quarks, i.e. charm or bottom, are important probes of the hot and dense medium created in relativistic heavy ion collisions. Heavy quark-antiquark pairs are mainly produced in initial hard scattering processes of partons. While some of the produced pairs form bound quarkonia, the vast majority hadronize into particles carrying open heavy flavor. Heavy quark production has been studied by the PHENIX experiment at RHIC via measurements of single leptons from semi-leptonic decays in both the electron channel at mid-rapidity and in the muon channel at forward rapidity. A large suppression and azimuthal anisotropy of single electrons have been observed in Au + Au collisions at 200 GeV. These results suggest a large energy loss and flow of heavy quarks in the hot, dense matter. The PHENIX experiment has also measured J/ψ production at 200 GeV in p + p, d + Au, Cu + Cu and Au + Au collisions, both at mid- and forward-rapidities, and additionally Cu + Au and U + U at forward-rapidities. In the most energetic collisions, more suppression is observed at forward rapidity than at central rapidity. This can be interpreted either as a sign of quark recombination, or as a hintmore »« less

Open Heavy Flavor and Quarkonia Results at RHIC

Journal Article Nouicer, Rachid - EPJ Web of Conferences

RHIC experiments carry out a comprehensive physics program which studies open heavy flavor and quarkonium production in relativistic heavy-ion collisions. The discovery at RHIC of large high-pT suppression and flow of electrons from heavy quarks flavors have altered our view of the hot and dense matter formed in central Au + Au collisions at √S_NN = 200 GeV. These results suggest a large energy loss and flow of heavy quarks in the hot, dense matter. In recent years, the RHIC experiments upgraded the detectors; (1) PHENIX Collaboration installed silicon vertex tracker (VTX) at mid-rapidity region and forward silicon vertex trackermore »« less

Recent Heavy Flavor Results Utilizing the FVTX in PHENIX at RHIC

Journal Article Li, Xuan - Journal of Physics. Conference Series

Heavy-flavor and quarkona production are important hard probes to test Quantum Chromodynamics (QCD) and measure the properties of the Quark Gluon Plasma (QGP) created in high energy heavy ion collisions. The new PHENIX mid- and forward-rapidity silicon vertex detectors provide precise Distance of Closest Approach (DCA) determination, allowing charm and bottom yields identification, and improve di-muon mass resolution for charmonia studies. The relative ψ(2S) over J/ψ (1S) yields measured in p+p, p+Al and p+Au data at $$\sqrt{s}$$ =200 GeV help us to understand final state effects on the charmonia production. Direct access to B-meson production has been enabled via measurementsmore »« less

Heavy Flavor Production at PHENIX at RHIC

Journal Article Xiaorong, Wang - AIP Conference Proceedings

A study of heavy flavor production in different collision systems in various kinematic regions presents an opportunity to probe cold nuclear medium and hot dense matter effects. Results from the PHENIX experiment on J/{psi} and open charm production in Au+Au and Cu+Cu collisions at {radical}(s{sub NN}) =200 GeV are presented. The data show strong J/{psi} suppression in central AA collisions, similar to NA50 results, and strong suppression in high pT open charm production. The J/{psi} production in Au+Au and d+Au collisions is compared to understand the cold nuclear medium effects. The data show significant cold nuclear effects in charm productionmore »« less

J/psi suppression at forward rapidity in Au + Au collisions at sqrt(s_NN)=200 GeV

Journal Article Adare, A; Experiment, PHENIX - Physical Review, C (Nuclear Physics)

Heavy quarkonia are observed to be suppressed in relativistic heavy-ion collisions relative to their production in p+p collisions scaled by the number of binary collisions. In order to determine if this suppression is related to color screening of these states in the produced medium, one needs to account for other nuclear modifications including those in cold nuclear matter. In this paper, we present new measurements from the PHENIX 2007 data set of J/{psi} yields at forward rapidity (1.2 < |y| < 2.2) in Au+Au collisions at {radical}s{sub NN} = 200 GeV. The data confirm the earlier finding that the suppressionmore »« less
