Midrapidity $\phi$ production in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}=130\mathrm{}$ GeV

We present the first measurement of midrapidity vector meson $\phi$ production in Au+Au collisions at RHIC $(\sqrt{s_{\mathrm{NN}}}=130\mathrm{}\hspace{0.5em}\mathrm{GeV})$ from the STAR detector. For the 11% highest multiplicity collisions, the slope parameter from an exponential fit to the transverse mass distribution is $T=379\mathrm{}\pm 50\left(\mathrm{stat}\right)\pm 45\left(\mathrm{syst}\right)\hspace{0.5em}\mathrm{MeV},$ the yield $dN/dy=5.73\mathrm{}\pm 0.37\left(\mathrm{stat}\right)\pm 0.69\left(\mathrm{syst}\right)$ per event, and the ratio $N_{\phi }{/N}_{h^{-}}$ is found to be $0.021\pm 0.001\left(\mathrm{stat}\right)\pm 0.004\left(\mathrm{syst}\right).\mathrm{}$ The measured ratio $N_{\phi }{/N}_{h^{-}}$ and T for the $\phi$ meson at midrapidity do not change for the selected multiplicity bins.
