Direct photon production in polarized hadron collisions at collider and fixed target energies

A. P. Contogouris, Z. Merebashvili

Recently determined next-to-leading order sets of polarized parton distributions are used to study large-p_T $\vec{p}\vec{p}\to \gamma +X$ at $\sqrt{s}=38,100and500GeV$. Cert…
