The production of W+W- pairs in proton-antiproton colliders

We present the predictions of the Glashow-Weinberg-Salam (GWS) model for the total cross-section and the angular and invariant-mass differential cross sections for the reaction panti p->W+W-X. We contrast these GWS predictions with those obtained by varying the anomalous magnetic moment of the W(kappa), the analogue for the ZWW coupling (kappasub(Z)) and the relative strength of the γWW and ZWW couplings (ω) from their GWS values. We find that changes in these parameters produce significant changes in both the total cross section and the angular and invariant mass differential cross sections. We also present the angular distribution of the decay leptons (W+->l+ νsub(l)) and find in all cases it closely mirrors the W+ angular distribution. We have given the intermediate results for the dominant quark subprocesses (uanti u->W+W-, danti d->W+W-). (orig.)
