J/Psi -> ee and J/Psi -> μμMeasurements in AuAu and pp Collisions at sqrt{s_{NN}} = 200 GeV

Abstract

First results are presented from J/Psi -> ee and J/Psi -> μμmeasurements by the PHENIX experiment at RHIC. These results are from a preliminary analysis of dielectrons from AuAu and pp data and dimuons from pp data measured in the RHIC run 2. A total cross section for J/Psi production in sqrt{s} = 200 GeV pp collisions of 3.8 \pm 0.6 (stat) \pm 1.3 (sys) microbarns is found. The J/Psi -> ee yield is presented versus number of binary collisions.
