Single Spin Transverse Asymmetries of Neutral Pions at Forward Rapidities in sqrt(s) = 62.4 GeV Polarized Proton Collisions in PHENIX

Abstract

In the RHIC run of 2006, PHENIX recorded data from about 20/nb of transversely polarized p+p collisions at sqrt(s) = 62.4 GeV and polarization of about 50%. Also in this last run PHENIX successfully commissioned a new lead-tungstate based electromagnetic calorimeter, the Muon Piston Calorimeter (MPC), covering 2 pi in azimuth and 3.1<eta<3.7. The forward coverage allows PHENIX to measure high x_F pi^0 production. We present the current status of the analysis for the single inclusive pi^0 transverse asymmetry A_N at forward rapidities in PHENIX.
