Description

Heavy flavor quarks are produced in the early stages of heavy ion collisions and serve as an important probe of the strongly interacting deconfined medium believed to be produced in these collisions at RHIC. Measuring observables such as Nuclear Modification Factor and Elliptic Flow for open heavy flavor production can help in quantifying medium effects. Measurement of heavy flavor production in p+p collision is an absolutely necessary baseline measurement for nuclear modification factor. On the other hand, measurements of heavy quark production in p+p collisions provides an important cross-check of pQCD calculations. PHENIX has a unique ability to measure single lepton spectra both at |eta|< 0.35 and at 1.4<|eta|<1.9 rapidity ranges, with its Central and Muon arms, respectively. Single leptons are used to tag the production of heavy flavor quarks via semileptonic decay of heavy flavor mesons (D,B). The most recent PHENIX single lepton measurements for different colliding ion systems will be presented and compared to the most recent available theoretical model predictions.
