Abstract

Measurement of electrons from heavy quarks by PHENIX has been done for various collision species and energy.PHENIX has measured single electron spectra from heavy flavor decays in Au+Au collisions at sqrtSNN=200sqrt{S_{NN}} = 200 GeV.The measurement of heavy flavor production for p + p in PHENIX has also been measured which provided the baseline for studying hot and dense matter effects in heavy ion reactions. In Au + Au we observe a strong suppression of single electron compared with scaled p + p which challenges radiative energy loss models because heavy quarksare expected to radiate less than light quarks. Measurements done in Cu + Cu collisions by PHENIX provide a measurement for species of intermediate size between p + p and Au + Au, while measurements in Au + Au collisions at sqrtSNN=62.4sqrt{S_{NN} = 62.4} GeV provide a measurement at lower energy.

Comments

Better plotsmanship for Fig. 3. Corrected typos and added proper reference for Converter method of determining conversion electrons. Rephrasing few sentences to convey the Physics message more clearer to the reader
