Gluon polarization in transversely polarized nucleons and jet spin asymmetries at RHIC
J. Soffer, O. V. Teryaev
Abstract
We derive the analog of the Wandzura-Wilczek relation for the light-cone distributions of polarized gluons in a transversely polarized nucleon. The short distance cross-section is entirely due to the intrinsic transverse momenta of gluon in the nucleon, in complete analogy to the quark case. Numerical estimate for the double spin transverse asymmetries at RHIC are presented.
