J/ψ measurements in the STAR experiment

الأصل · EN

In this paper, we present recent STAR J/ψ results. J/ψ nuclear modification factors (RAA) in Au+Au collisions at √sNN = 200, 62.4 and 39 GeV and in U+U collisions at √sNN = 193 GeV are measured and compared to different theoretical calculations. We also report J/ψ elliptic flow (v₂) results in Au+Au collisions at √sNN = 200 GeV and the first ψ(2S) to J/ψ ratio measurement in p+p collisions at √s = 500 GeV.
