High-$p_T$ $J/\Psi$ production in p+p collisions at $\sqrt{s}$=200 GeV

ORAL

Abstract

We report our preliminary analysis of high-$p_T$ $J/\Psi \rightarrow e^+e^-$ production at $p_T \sim 6$ GeV/c at mid-rapidity in p+p collisions at $\sqrt{s}$=200 GeV. The datasets are from RHIC run V and VI, sampling more than a few hundreds(nb)$^{-1}$ of p+p collisions in a trigger on energy deposit in Electromagnetic Calorimeter with energy threshold of $\sim>$2.6GeV. This provides a baseline for future study of $J/\Psi$ suppression at high-$p_T$ in heavy-ion collisions at RHIC.
