Title: Measurements of WW and WZ Production in W plus jets Final States in p(p)over-bar Collisions

Abstract

We study WW and WZ production with {ell}{nu}qq ({ell} = e,{mu}) final states using data collected by the D0 detector at the Fermilab Tevatron Collider corresponding to 4.3 fb{sup -1} of integrated luminosity from p{bar p} collisions at {radical}s = 1.96 TeV. Assuming the ratio between the production cross sections {sigma}(WW) and {sigma}(WZ) as predicted by the standard model, we measure the total WV (V = W,Z) cross section to be {sigma}(WV) = 19.6{sub -3.0}{sup +3.2} pb and reject the background-only hypothesis at a level of 7.9 standard deviations. We also use b-jet discrimination to separate the WZ component from the dominant WW component. Simultaneously fitting WW and WZ contributions, we measure {sigma}(WW) = 15.9{sub -3.2}{sup +3.7} pb and {sigma}(WZ) = 3.3{sub -3.3}{sup +4.1} pb, which is consistent with the standard model predictions.
