Double spin asymmetry A_{LT} in direct photon production

High Energy Physics - Phenomenology 2015-06-04 v1

Abstract

We study the longitudinal-transverse double spin asymmetry ALTA_{LT} for direct photon production in nucleon-nucleon scattering by using the collinear twist-3 approach. This asymmetry, which, for instance, could be measured at RHIC, contains a complete set of collinear twist-3 correlation functions in a transversely polarized nucleon.
