Title: Dielectron Continuum Measurements in sqrt(s NN) = 200 GeV Au+Au and Cu+Cu Collisions at PHENIX

Abstract

The dielectron continuum measurement contains a variety of signals, including vector meson decays, hadron Dalitz decays, correlated semi-leptonic heavy flavor decays and direct virtual photon emission. Since electrons and positrons are not affected by the strong force, the resulting signals occur over the full time evolution of the collision. Direct virtual photons are emitted throughout the collision and provide information on the temperature progression of the system. Light vector mesons and correlated heavy flavor production may experience medium modification. Comparison between the PHENIX Au+Au data and the new Cu+Cu data allows an investigation of surface area and volume effects on all dilepton signals. The status of the analysis in Cu+Cu collisions will be presented.
