Limits on anomalous WWγ and WWZ couplings from WW/W→Zeνjj production

Limits on anomalous WWγ and WWZ couplings from WW/W→Zeνjj production
Limits on anomalous WWγ and WWZ couplings are presented from a study of WW/W→Zeνjj events produced in p¯p collisions at √s=1.8TeV. Results from the analysis of data collected using the DØ detector during the 1993–1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992–1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous WWγ and WWZ couplings. With the assumption that the WWγ and WWZ couplings are equal, we obtain −0.34<λ<0.36 (with Δκ=0) and −0.43<Δκ<0.59 (with λ=0) at the 95% confidence level for a form-factor scale Λ=2.0TeV.

Abstract

Limits on anomalous WWγ and WWZ couplings are presented from a study of WW/W→Zeνjj events produced in p¯p collisions at √s=1.8TeV. Results from the analysis of data collected using the DØ detector during the 1993–1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992–1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous WWγ and WWZ couplings. With the assumption that the WWγ and WWZ couplings are equal, we obtain −0.34<λ<0.36 (with Δκ=0) and −0.43<Δκ<0.59 (with λ=0) at the 95% confidence level for a form-factor scale Λ=2.0TeV.
