Abstract
We report the first measurement of transverse single-spin asymmetries in J/ψ production from transversely polarized p+p collisions at √s=200GeV with data taken by the PHENIX experiment in 2006 and 2008. The measurement was performed over the rapidity ranges 1.2<

y

<2.2 and

<0.35 for transverse momenta up to 6GeV/c. J/ψ production at the Relativistic Heavy Ion Collider is dominated by processes involving initial-state gluons, and transverse single-spin asymmetries of the J/ψ can provide access to gluon dynamics within the nucleon. Such asymmetries may also shed light on the long-standing question in QCD of the J/ψ production mechanism. Asymmetries were obtained as a function of J/ψ transverse momentum and Feynman-x, with a value of -0.086±0.026stat±0.003syst in the forward region. This result suggests possible nonzero trigluon correlation functions in transversely polarized protons and, if well defined in this reaction, a nonzero gluon Sivers distribution function. © 2010 The American Physical Society.
