Search for Anomalous $WW$ and $WZ$ production at {DØ}

Abstract

We present a preliminary result from a search for anomalous $WW$ and $WZ$ production in $p\bar{p}$ collisions at $\sqrt{s}=1.8$ TeV using $p\bar{p}\rightarrow eνjj$ events observed during the 1992--1993 run of the Fermilab Tevatron collider. A fit to the $p_T$ spectrum of $W(eν)$ yields direct limits on the CP--conserving anomalous $WWγ$ and $WWZ$ coupling parameters of $-0.89<Δκ<1.07~~(λ=0)$ and $-0.66<λ<0.67~~(Δκ=0)$ at the $95\ \%$ confidence level, assuming that the $WWZ$ coupling parameters are equal to the $WWγ$ coupling parameters, and a form factor scale $Λ=1.5$~TeV.
