SUSY QCD corrections to W γ production in polarized hadronic collisions

We present the calculation of the supersymmetric QCD correction to $W \gamma$ production process in polarized proton-antiproton collisions at the TeV energy region. We find that the correction can reach 1.2% at parton level with favorable mass values of squarks and gluino, which is comparable with the virtual correction part of the conventional QCD. The production rates for different polarized $p \bar{p}$ collisions are also compared.
