No. of bitstreams: 0 Previous issue date: 2005-04-22; We present a measurement of the W boson pair-production cross section in pp̄ collisions at a center-of-mass energy of √s = 1.96 TeV. The data, collected with the Run II D0 detector at Fermilab, correspond to an integrated luminosity of 224-252 pb-1 depending on the final state (ee, eμ, or μμ). We observ...
