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

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