Abstract
Limits on the anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings are presented from a simultaneous fit to the data samples of three gauge boson pair final states in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}:$ $W\ensuremath{\gamma}$ production with the $W$ boson decaying to $e\ensuremath{\nu}$ or \ensuremath{\mu}\ensuremath{\nu}, $W$ boson pair production with both of the $W$ bosons decaying to $e\ensuremath{\nu}$ or \ensuremath{\mu}\ensuremath{\nu}, and $\mathrm{WW}$ or $\mathrm{WZ}$ production with one $W$ boson decaying to $e\ensuremath{\nu}$ and the other $W$ boson or the $Z$ boson decaying to two jets. Assuming identical $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings, 95% C.L. limits on the anomalous couplings of $\ensuremath{-}0.30<\ensuremath{\Delta}\ensuremath{\kappa}<0.43$ $(\ensuremath{\lambda}=0)$ and $\ensuremath{-}0.20<\ensuremath{\lambda}<0.20$ $(\ensuremath{\Delta}\ensuremath{\kappa}=0)$ are obtained using a form factor scale $\ensuremath{\Lambda}=2.0\mathrm{TeV}.$ Limits found under other assumptions on the relationship between the $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings are also presented.
