Search forWBoson Pair Production inpp¯Collisions ats=1.8TeV

The results of a search for $W$ boson pair production in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{}\mathrm{TeV}$ with subsequent decay to dilepton ( $e\mu ,ee$, and $\mu \mu$) channels are presented. One event is observed with an expected background of $0.56\pm 0.13$ events with an integrated luminosity of approximately $14{\mathrm{pb}}^{-1\mathrm{}}$. Assuming equal strengths for the $\mathrm{WWZ}$ and $\mathrm{WW}\gamma$ gauge boson coupling parameters $\kappa$ and $\lambda$, limits on the $\mathrm{CP}$-conserving anomalous coupling constants are $-2.6<\Delta \kappa <2.8\mathrm{}$ and $-2.1<\lambda <2.1\mathrm{}$ at the 95% confidence level.
