Description
Heavy flavor quarks have been suggested as excellent probes to study the properties of the hot and dense nuclear matter created in high-energy heavy- ion collisions. In this regard, high precision measurements of heavy flavor production in p+p collisions are also important as they provide a reference to study the medium effects in heavy-ion collisions. In this poster, we will present the latest results on electrons produced from semileptonic decays of open heavy flavor hadrons in p+p and Au+Au collisions at √sNN=200 GeV. The p+p results are extracted from data taken by the STAR experiment at the Relativistic Heavy Ion Collider in the year 2012, which have a highly improved precision than previous results over a wider range of transverse momentum, 0.2 < pT<12 GeV/c. With this new p+p baseline, improved nuclear modification factors $R_{AA}$ in Au+Au collisions are also obtained and compared with theoretical model calculations.
