Limits on anomalous WWy and WWZ couplings

Abstract

Limits on the anomalous WWγ and WWZ couplings are presented from a simultaneous fit to the data samples of three gauge boson pair final states in pp collisions at fs= 1.8 TeV: W y production with the W boson decaying to ev or pv, W boson pair production with both of the W bosons decaying to ev or μv, and WW or WZ production with one W boson decaying to e v and the other W boson or the Z boson decaying to two jets. Assuming identical WWγ and WWZ couplings, 95% C.L. limits on the anomalous couplings of -0.30 <<0.20 (AK=0) are obtained using a form factor scale A = 2.0 TeV. Limits found under other assumptions on the relationship between the WWy and WWZ couplings are also presented. © 1998 The American Physical Society.
