Search for AnomalousWWandWZProduction inpp¯Collisions ats=1.8TeV

We present results from a search for anomalous $\mathrm{WW}$ and $\mathrm{WZ}$ production in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}$. We used $p\overline{p}\to e\nu \mathrm{jjX}$ events observed during the 1992–1993 run of the Fermilab Tevatron collider, corresponding to an integrated luminosity of $13.7\pm 0.7{\mathrm{pb}}^{-1\mathrm{}}$. A fit to the transverse momentum spectrum of the $W$ boson yields direct limits on the CP-conserving anomalous $\mathrm{WW}\gamma$ and $\mathrm{WWZ}$ coupling parameters of $-0.9<\Delta \kappa <1.1\mathrm{}$ (with $\lambda =0\mathrm{}$) and $-0.6<\lambda <0.7\mathrm{}$ (with $\Delta \kappa =0\mathrm{}$) at the 95% confidence level, for a form factor scale $\Lambda =1.5\mathrm{TeV}$, assuming that the $\mathrm{WW}\gamma$ and $\mathrm{WWZ}$ coupling parameters are equal.
