$ϕ$ meson production in d + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV

Abstract

We present the preliminary results on $ϕ$ meson production in the $ϕ\to K^{+}K^{-}$ and $ϕ\to e^{+}e^{-}$ decay channels measured at mid-rapidity in $\sqrt{s}$ = 200 GeV d + Au collisions at RHIC by the PHENIX experiment. The transverse mass spectra were obtained in both channels. The extracted $ϕ$ yields are found to be consistent with each other. The results are compared to the measurements in Au + Au collisions at the same center of mass energy.
