摘要

Measurement by the STAR experiment at RHIC of the cold nuclear matter (CNM) effects experienced by inclusive J/psi at mid-rapidity in 0-100% p+Au collisions at root s(NN) = 200 GeV is presented. Such effects are quantified utilizing the nuclear modification factor, R-pAu, obtained by taking a ratio of J/* yield in p+Au collisions to that in p+p collisions scaled by the number of binary nucleon-nucleon collisions. The differential J/psi yield in both p+p and p+Au collisions is measured through the dimuon decay channel, taking advantage of the trigger capability provided by the Muon Telescope Detector in the RHIC 2015 run. Consequently, the J/psi R-pAu is derived within the transverse momentum (p(T)) range of 0 to 10 GeV/c. A suppression of approximately 30% is observed for p(T) <= 2 GeV/c, while J/psi R-pAu becomes compatible with unity for p(T) greater than 3 GeV/c, indicating the J/psi yield is minimally affected by the CNM effects at high p(T). Comparison to a similar measurement from 0-20% central Au+Au collisions reveals that the observed strong J/psi suppression above 3 GeV/c is mostly due to the hot medium effects, providing strong evidence for the formation of the quark-gluon plasma in these collisions. Several model calculations show qualitative agreement with the measured J/psi R-pAu, while their agreement with the J/psi yields in p+p and p+Au collisions is worse. (C) 2022 The Author(s).
