$\varphi$ meson production in Au - Au collisions at $\sqrt{s_{NN}}$ = 200 GeV

A simultaneous measurement of the $\varphi$ meson via its $K^{+}{K}^{-}$ and $e^{+}{e}^{-}$ decay channels was performed in Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV at mid-rapidity by the PHENIX experiment. The preliminary minimum bias yields $d{N}_{\varphi }\mathrm{/}dy$ in the kaon and electron channels are $2.01\pm 0.22(stat\mathrm{.}{)}_{-0.52}^{+1.01}(syst\mathrm{.})$ and $5.4 \pm 2.5 (stat) ^{+3.4}_{-2.8} (syst.)$, respectively. The centrality dependence of the yield in the $K^{+}{K}^{-}$ channel is presented.
