We present limits on anomalous WWZ and WW{gamma} couplings from a search for WW and WZ production in p{anti p} collisions at {radical}(s)=1.8 TeV . We use p{anti p}{r_arrow}e{nu}jjX events recorded with the D0 detector at the Fermilab Tevatron Collider during the 1992{endash}1995 run. The data sample corresponds to an integrated luminosity of 96.0{plus_minus}5.1 pb{sup {minus}1}. Assuming identical WWZ and WW{gamma} coupling parameters, the 95{percent} C.L.limits on the CP-conserving couplings are {minus}0.33{lt}{lambda}{lt}0.36 ({Delta}{kappa}=0) and {minus}0.43{lt}{Delta}{kappa}{lt}0.59 ({lambda}=0), for a form factor scale {Lambda}=2.0 TeV . Limits based on other assumptions are also presented. {copyright} {ital 1997} {ital The American Physical Society}
