Abstract
We report results on J/ψ-hadron azimuthal angular correlations in 200 GeV p+p collision in the STAR experiment at RHIC. The extracted B-hadron feed-down contribution to inclusive J/ψ yield is found to be 10-25% in and has no significant center-of-mass energy dependence from RHIC to LHC. The pT spectrum of charged hadrons associated with high-pT J/ψ triggers on the away side is found to be consistent with that from di-hadron correlations. J/ψ signal from Au+Au 39 GeV data will also be presented to demonstrate STARʼs J/ψ capability at RHIC low energy run.
