Limits on anomalous trilinear gauge couplings from $W W \to e^ + e^ - $, $W W \to e^\pm \mu^\mp$, and $W W \to \mu^ + \mu^ - $ events from $p\bar p $ collisions at $\sqrt s $ 1.96-TeV

Limits are set on anomalous WWgamma and WWZ trilinear gauge couplings using W+W- -> e+e-, W+W- -> e mu, and W+W- -> mu+mu- events. The data set was collected by the Run II D0 detector at the Fermilab Tevatron Collider and corresponds to approximately 250 inverse pb of integrated luminosity at sqrt(s) = 1.96 TeV. Under the assumption that the WWgamma couplings are equal to the WWZ couplings and using a form factor scale of Lambda = 2.0 TeV, the combined 95% C.L. one-dimensional coupling limits from all three channels are -0.32 < Delta kappa < 0.45 and -0.29 < lambda < 0.30.
