【 摘 要 】

We present the rst J/ψ and measurements in the di-muon decay channel at mid-rapidity at RHIC using the newly installed Muon Telescope Detector. In p+p collisions at √s = 500 GeV, inclusive J/ψ cross section can be described by CGC+NRQCD and NLO NRQCD model calculations for 0 TAAcan be qualitatively described by transport models including dissociation and regeneration with a tension at high pT; and (iii) hint of less melting of ϒ(2S + 3S) relative to ϒ(1S) at RHIC compared to that at LHC.
