Abstract
We present the first measurement of mid-rapidity vector meson production in collisions at RHIC ( GeV) from the STAR detector. For the 11% most central collisions, the slope parameter from an exponential fit to the transverse mass distribution is ~37951(stat) 45(syst)~MeV, the yield 0.37(stat) 0.57(syst) per event and the ratio is found to be 0.0210.001(stat) 0.03(syst). We currently place the value of the ratio between 0.10 and 0.16. The measured ratios and , as well as for the meson at mid-rapidity do not change for the selected centrality bins.
