Abstract
We present a measurement of the W+W- production cross section using 184 pb(-1) of p (p) over bar collisions at a center-of-mass energy of 1.96 TeV collected with the Collider Detector at Fermilab. Using the dilepton decay channel W+W--> l(+)nu l(-)(nu) over bar, where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background of 5.0(-0.8)(+2.2) events. The resulting W+W- production cross-section measurement of sigma(p (p) over bar -> W+W-)=14.6(-5.1)(+5.8)(stat)(-3.0)(+1.8)(syst)+/- 0.9(lum) pb agrees well with the standard model expectation.
