Recall a prediction on J/ψ nuclear modification factor for STAR measurements
نویسنده
چکیده
STAR collaboration has offered eminent nuclear modification factor of J/ψ at high pT and midrapidity produced in Cu-Cu collisions at √ sNN = 200 GeV. Recalling a prediction we can understand that the feature of high-pT nuclear modification factor is related to cc̄ produced by 2 → 1 and 2 → 2 partonic processes in deconfined matter particularly in the prethermal stage and to the recombination of c and c̄. The nuclear modification factor at high pT is sensitive to the earliest form of deconfined matter that does not have a temperature.

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 کاملHeavy-flavour and quarkonium measurements in Pb–Pb collisions at √ sNN = 2.76 TeV with ALICE
We report on the latest results on heavy-flavour and J/ψ production at both midrapidity and forward rapidity, in Pb–Pb collisions at √ sNN = 2.76 TeV, measured with the ALICE experiment at the LHC. We present measurements of the nuclear modification factor for open heavy-flavours and J/ψ and compare these results to model predictions. Preliminary results on the elliptic flow of D mesons and J/ψ...
متن کاملA look at the influence of the J/ψ transverse momentum on shadowing
Stringent physical constraints relate the J/ψ produced at a given transverse momentum pT to the Bjorken-x of the initial gluons. We present a new approach which takes them into account in order to explicitely investigate the pT -dependence of the shadowing effect on the J/ψ production. Using the J/ψ rapidity and pT spectra extracted from √ s= 200 GeV p + p data from PHENIX, we build a Glauber M...
متن کاملJ/ψ production and nuclear effects for d+Au and p+p collisions in PHENIX
PHENIX has measured J/ψ production at backward, central and forward rapidities both in p+p and d+Au collisions at √ sNN = 200 GeV during the third run of the RHIC collider. From the p+p collisions, we measure the total J/ψ cross section. From the d+Au collisions, we compute the nuclear modification factor versus transverse momentum, rapidity and centrality. All results presented here are prelim...
متن کاملCharmonium production measured in PbPb and pp collisions by CMS
The Compact Muon Solenoid (CMS) is fully equipped to measure hard probes in the di-muon decay channel in the high multiplicity environment of nucleus-nucleus collisions. Such probes are especially relevant for studying the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. CMS is able to distinguish non-prompt from prompt J/ψ in pp...
