Description

We present the first measurement of midrapidity vector meson φ production in Au+Au collisions at RHIC (√(sNN)=130 GeV) from the STAR detector. For the 11% highest multiplicity collisions, the slope parameter from an exponential fit to the transverse mass distribution is T=379±50(stat)±45(syst) MeV, the yield dN/dy=5.73±0.37(stat)±0.69(syst) per event, and the ratio Nφ/Nh- is found to be 0.021±0.001(stat)±0.004(syst). The measured ratio Nφ/Nh- and T for the φ meson at midrapidity do not change for the selected multiplicity bins
