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