Abstract
We present first evidence for WW+WZ production in lepton+jets final states at a hadron collider. The data correspond to 1.07 fb<SUP>-1</SUP> of integrated luminosity collected with the D0 detector at the Fermilab Tevatron in pp̅ collisions at √s=1.96 TeV. The observed cross section for WW+WZ production is 20.2±4.5 pb, consistent with the standard model and more precise than previous measurements in fully leptonic final states. The probability that background fluctuations alone produce this excess is < 5.4x10<SUP>-6</SUP>, which corresponds to a significance of 4.4 standard deviations.
