The PHENIX experiment presents results from the Relativistic Heavy Ion Collider 2005 run with polarized proton collisions at sqrt(s)=200 GeV, for inclusive {pi}{sup 0} production at midrapidity. Unpolarized cross section results are given for transverse momenta p{sub T}=0.5 to 20 GeV/c, extending the range of published data to both lower and higher p{sub T}. The cross section is described well for p{sub T} 2 GeV/c, by perturbative QCD. Double helicity asymmetries ALL are presented based on a… Expand

PHENIX has measured parity-violating single helicity asymmetry AL for each polarized beam, which was consistent with zero within statistical uncertainty, in all pT bins
