We discuss Wγ production in polarized p p collisions at RHIC energy. We point out that the RHIC collider has two advantages over other hadron colliders to measure the characteristic feature of Wγ production: (1) the RHIC energy is not so high and (2) the polarized beams are available. We calculate the tree level cross section for Wγ production using a generic spin basis for W and discuss both t...
