ABSTRACT

Recent results on low mass dilepton measurements from the PHENIX experiment are reported. Invariant mass spectra of ø→e+e are measured for the first time in Au-Au collisions at √sNN= 200 GeV in Run2. In d-Au collisions, the yields and MT slopes of both ø→ e+e and ø→K+K are measured. Both results are consistent with each other within errors. In the future, a Hadron Blind Detector will be installed in PHENIX which will enhance our capabilities of rejecting external photon conversions and Dalitz pairs, that will result in a significant reduction of the large combinatorial background.
