Evidence of WW and WZ Production with lepton plus jets Final States in pp Collisions at root s=1.96 TeV (Art. No. 161801)

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(-1) of integrated luminosity collected with the D0 detector at the Fermilab Tevatron in pp collisions at root 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(-6), which corresponds to a significance of 4.4 standard deviations.
