Low mass dilepton production at RHIC energies

Authors:	K Ozawa

Abstract:	Recent results on low mass dilepton measurements from the PHENIX experiment are reported. Invariant mass spectra of $\phi\rightarrow e^ + e^-$ are measured for the first time in Au-Au collisions at $\sqrt{s_{NN}} = 200$ GeV in Run2. In d-Au collisions, the yields and M_T slopes of both $\phi\rightarrow e^ + e^-$ and $\phi \rightarrow K^ + K^-$ 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. ^* Deceased $^{\dag }$ Spokesperson
