Scientific paper

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 $p\bar{p}\rightarrow e\nu jj$ events observed during the 1992--1993 run of the Fermilab Tevatron collider. A fit to the $p_T$ spectrum of $W(e\nu)$ yields direct limits on the CP--conserving anomalous $WW\gamma$ and $WWZ$ coupling parameters of $-0.89<\Delta\kappa<1.07~~(\lambda=0)$ and $-0.66<\lambda<0.67~~(\Delta\kappa=0)$ at the $95\ \%$ confidence level, assuming that the $WWZ$ coupling parameters are equal to the $WW\gamma$ coupling parameters, and a form factor scale $\Lambda=1.5$~TeV.
