Limits on WWZ and WWγ couplings from pp̅→evjjX events at √s=1.8 TeV

Abstract

We present limits on anomalous WWZ and WWγ couplings from a search for WW and WZ production in pp̅ collisions at √s=1.8TeV. We use pp̅→evjjX events recorded with the D0 detector at the Fermilab Tevatron Collider during the 1992–1995 run. The data sample corresponds to an integrated luminosity of 96.0±5.1pb^-1. Assuming identical WWZ and WWγ coupling parameters, the 95% C.L. limits on the CP-conserving couplings are -0.33<λ<0.36 (Δκ=0) and -0.43<Δκ<0.59 (λ=0), for a form factor scale Λ=2.0TeV. Limits based on other assumptions are also presented.
