In these proceedings, we present the latest measurements of J/ψ and ϒ by the STAR experiment. The J/ψ and ϒ production measured in p+p collisions provide new baselines for similar measurements in Au+Au collisions, while the measurements in p+Au collisions can help quantify the cold nuclear matter effects. The J/ψ υ2 is measured in both U+U and Au+Au collisions to place constraints on the amount of J/ψ arising from recombination of deconfined charm and anti-charm pairs. Furthermore, the nuclear modification factors for ground and excited ϒ states as a function of transverse momentum and centrality are presented, and compared to those measured at the LHC as well as to theoretical calculations.

This paper reviews recent experimental results on hard probes in heavy-ion collisions from the ALICE and STAR Collaboration. These studies include various observables characterizing jet properties like nuclear modification factors, recoil jet yields, di-jet and photon-jet energy imbalance, and the observables characterizing jet properties like jet fragmentation function and jet shapes; and measurements of high-pT charged hadrons from jet fragmentation and triggered particle correlations will be highlighted.

Modification Factor

The PHENIX experiment at RHIC measured ω, η and [Formula: see text]-meson production at high pT in p + p, d + Au and Au + Au collisions at [Formula: see text]. Measurements performed in different hadronic decay channels give consistent results. The measured ratios of all three mesons to π0 are found to be flat as a function of pT in p + p collisions and equal to ω/π0 = 0.81 ± 0.02 ± 0.07, η/π0 = 0.48 ± 0.02 ± 0.02 and [Formula: see text]. Nuclear modification factor measured for ω-mesons in central Au + Au collisions is RAA = 0.4 ± 0.15.
