摘要
Electron-positron pairs are effective probes for investigating the hot, dense matter created in RHIC collisions because they carry no color charge and therefore, once created, do not interact strongly with the medium. As a result, they retain characteristics of the full time evolution and dynamics of the system. The PHENIX experiment has presented dielectron continuum spectra for p+p, Cu+Cu and Au+Au collisions at root s(NN) = 200 GeV. PHENIX has recently measured dielectrons in d+Au collisions to serve as a control experiment to the heavy ion collisions allowing us to disentangle any cold nuclear effects from those due to the quark gluon plasma. First results are presented here.
