Abstract

Measurements of transverse-single-spin asymmetries (AN) in p+p collisions at s=62.4 and 200 GeV with the PHENIX detector at the Relativistic Heavy Ion Collider are presented. At midrapidity, AN is measured for neutral pion and eta mesons reconstructed from diphoton decay, and, at forward rapidities, neutral pions are measured using both diphotons and electromagnetic clusters. The neutral-pion measurement of AN at midrapidity is consistent with zero with uncertainties a factor of 20 smaller than previous publications, which will lead to improved constraints on the gluon Sivers function. At higher rapidities, where the valence quark distributions are probed, the data exhibit sizable asymmetries. In comparison with previous measurements in this kinematic region, the new data extend the kinematic coverage in s and pT, and it is found that the asymmetries depend only weakly on s. The origin of the forward AN is presently not understood quantitatively. The extended reach to higher pT probes the transition between transverse momentum dependent effects at low pT and multiparton dynamics at high pT.
