Testing the Higgs Sector and the Three Vector Boson Coupling with Electroweak Boson Pairs

Abstract

Electroweak vector boson pairs can be used to test the Higgs sector and the vector boson self-interactions of the Standard Model. They also constitute a background to new physics signals at future colliders. This is illustrated by vector boson pair production at large transverse momentum in hadronic collisions which may be a background which is relevant for Higgs tagging. The usefulness of electroweak boson pairs to probe the structure of the three vector boson vertex is demonstrated by W γ production at the Tevatron. For an integrated luminosity of 100 pb−1 the WW γ vertex can be measured with 25–40% accuracy in \(p\bar p \) collisons at \(\sqrt s = 1.8TeV\).
