Abstract
In recent years, PHENIX has studied many important observables related to heavy-flavor physics through their leptonic decay measurements including the invariant yield of electrons from nonphotonic sources, and prompt single muons, both of which are dominated by D and B mesons. Charm and beauty cross-sections were measured and compared through single lepton, and lepton–hadron correlations in p + p collisions at GeV. Observables for quarkonia production such as invariant yield and polarization were also measured in p + p collisions. In Au+Au collisions, preliminary results for the RAA for single electrons and a 90% CL upper limit for the suppression of ϒs were produced. And in d+Au collisions, a preliminary RCP study for J/ψ production in different centrality ranges was extracted.
