摘要：

J/psi suppression has long been considered a sensitive signature of the formation of the Quark-Gluon Plasma (QGP) in relativistic heavy-ion collisions. In this letter, we present the first measurement of inclusive J/psi production at mid-rapidity through the dimuon decay channel in Au+Au collisions at root s(NN) = 200 GeV with the STAR experiment. These measurements became possible after the installation of the Muon Telescope Detector was completed in 2014. The J/psi yields are measured in a wide transverse momentum (p(T)) range of 0.15 GeV/c to 12 GeV/c from central to peripheral collisions. They extend the kinematic reach of previous measurements at RHIC with improved precision. In the 0-10% most central collisions, the J/psi yield is suppressed by a factor of approximately 3 for p(T) > 5 GeV/c relative to that in p + p collisions scaled by the number of binary nucleon-nucleon collisions. The J/psi nuclear modification factor displays little dependence on p(T) in all centrality bins. Model calculations can qualitatively describe the data, providing further evidence for the color-screening effect experienced by J/psi mesons in the QGP.(C) 2019 The Author(s).
