Vector boson Pair Production at Supercolliders; useful approximate helicity amplitudes

High Energy Physics - Phenomenology 2019-08-17 v2

Abstract

We study vector boson pair production at LHCLHC and SSCSSC, taking into account the effects generated by the anomalous vector boson and Higgs couplings induced by the operators OW{\cal O}_W and OUW{\cal O}_{UW}, which are the only dim=6 operators preserving SU(2)cSU(2)_c. These operators lead to enhanced production of transverse vector bosons, as opposed to the enhanced production of longitudinal gauge bosons, induced in case MH\gsim1 TeVM_H\gsim 1\ TeV, by dim=4 terms already existing in the Standard Model lagrangian. For vector boson pair masses larger than 1 TeV1\ TeV, we establish very simple approximate expressions for the standard as well as the non-standard helicity amplitudes for qqˉq\bar q annihilation and vector boson fusion, which accurately describe the physics. These expressions should simplify the experimental search for such interactions. We finally discuss the observability and the disentangling of these interactions.
