Wino and zino production in panti p collisions: First order supersymmetric QCD corrections

We compute the first order supersymmetric QCD correction to wino (W) and zino (Z) production in panti p collisions via subprocesses involving two massless partons inside the nucleon or one massless parton and a massive SUSY parton (squark or gluino). The first order SQCD corrections to the rapidity dependence at CERN collider and Tevatron energies are found large (K≅2). The rates are important (≅10-2nb at √s=630 GeV and ≅10-1nb at √s=2 TeV), as soon as the W and Z production by squarks is allowed. Transverse momentum distributions are also given and their shape is found very sensitive to the presence of SUSY partons inside the nucleon. (orig.)
