Abstract

Here, we present the first results from the STAR MTD of mid-rapidity charmonium measurements via the di-muon decay channel in p+p, p+Au, and Au+Au collisions at √S _NN = 200 GeV at RHIC. The inclusive J/Ψ production cross section in p+p collisions can be described by the Non-Relativistic QCD (NRQCD) formalism coupled with the color glass condensate e ective theory (CGC) at low transverse momentum (p _T) and next-to-leading order NRQCD at high p _T. The nuclear modification factor in p+Au collisions for inclusive J/Ψ is below unity at low p _T and consistent with unity at high p _T, which can be described by calculations including both nuclear PDF and nuclear absorption e ects. The double ratio of inclusive J/Ψ and Ψ(2S) production rates for 0 < p _T < 10 GeV/c at mid-rapidity between p+p and p+Au collisions is measured to be 1.37 0.42 0.19. The nuclear modification factor in Au+Au collisions for inclusive J/Ψ shows significant J/Ψ suppression at high p _T in central collisions and can be qualitatively described by transport models including dissociation and regeneration contributions.

Energy dependence of J / ψ production in Au + Au collisions at $\sqrt{s_{N N}} = 39, 62.4 and 200 GeV$ s N N = 39 , 62.4 and 200 GeV

Journal Article Adamczyk, L. ; Adkins, J. K. ; Agakishiev, G. ; ... - Physics Letters B

The inclusive J/ψ transverse momentum spectra and nuclear modification factors are reported at mid-rapidity (|y|<1.0) in Au + Au collisions at √sNN = 39, 62.4 and 200 GeV taken by the STAR experiment. A suppression of J/ψ production, with respect to the production in p+p scaled by the number of binary nucleon–nucleon collisions, is observed in central Au + Au collisions at these three energies. No significant energy dependence of nuclear modification factors is found within uncertainties. The measured nuclear modification factors can be described by model calculations that take into account both suppression of direct J/ψ production due tomore »« less

Single-spin asymmetry of $J / ψ$ production in $p + p$ , $p + Al$ , and $p + Au$ collisions with transversely polarized proton beams at $\sqrt{s_{N N}} = 200 GeV$

We report the transverse single-spin asymmetries of J/ψ production at forward and backward rapidity, 1.2 < | y | < 2.2 , as a function of J/ψ transverse momentum (pT) and Feynman- x (x _F). The data analyzed were recorded by the PHENIX experiment at the Relativistic Heavy Ion Collider in 2015 from p+p, p+Al, and p+Au collisions with transversely polarized proton beams atmore »« less

Relative Modification of Prompt $ψ (2 S)$ and $J / ψ$ Yields from $p p$ to PbPb Collisions at $\sqrt{s_{N N}} = 5.02 TeV$

Journal Article Sirunyan, A. M. ; Tumasyan, A. ; Adam, W. ; ... - Physical Review Letters

The relative modification of the prompt ψ(2S) and J/ψ yields from pp to PbPb collisions, at the center-of-mass energy of 5.02 TeV per nucleon pair, is presented. The analysis is based on pp and PbPb data samples collected by the CMS experiment at the LHC in 2015, corresponding to integrated luminosities of 28.0 pb ^-1 and 464 μb ^-1, respectively. The double ratio of measured yields of prompt charmonia reconstructed through their decays into muon pairs, (N _ψ(2S)/N _J/ψ) _PbPb/(N _ψ(2S)/N _J/ψ) _pp, is determined as a function of PbPb collision centrality and charmonium transverse momentum p _T, in two kinematicmore »« less

Journal Article Aidala, C. ; Ajitanand, N. N. ; Akiba, Y. ; ... - Physical Review C

The fraction of J/Ψ mesons which come from B-meson decay, F _B→J/Ψ, is measured in this paper for J/Ψ rapidity 1.2 < |y| < 2.2 and p _T > 0 in p + p and Cu+Au collisions at √ ^sNN = 200 GeV with the PHENIX detector. The extracted fraction is F _B→J/Ψ = 0.025 ± 0.006 (stat) ± 0.010(syst) for p + p collisions. For Cu+Au collisions, F _B→J/Ψ is 0.094 ± 0.028 (stat) ± 0.037(syst) in the Au-going direction (-2.2 < y < -1.2) and 0.089 ± 0.026(stat) ± 0.040(syst) in the Cu-going direction (1.2 < y <more »« less
