Spin asymmetries in large- pT production of gauge bosons based on quantum chromodynamics and electroweak gauge model

Abstract

We make predictions for spin asymmetries in the production of gauge bosons, such as Z 0, W su± and γ, at large p T from the collision of longitudinally polarized hadrons using QCD perturbation theory and the electroweak gauge model in the framework of a hard scattering model. Asymmetries typically at the 20% and 4% level are predicted for the weak bosons and photon, respectively. Experimental tests should be possible in the near future, e.g., at Fermilab, ISABELLE and colliding SPS.
