Abstract

We present results of a search for W+W- production through the leptonic decay channel W+W- --> l(+)l(-) in <(p)over bar p> collision at root s = 1.8 TeV. In a 108 pb(-1) data sample recorded with the Collider Detector at Fermilab, five W+W- candidates are found with an expected standard model background of 1.2 +/- 0.3 events. The W+W- production cross section is measured to be sigma(<(p)over bar p> --> W+W-) = 10.2(-5.1)(+6.3)(stat) +/- 1.6(syst) pb, in agreement with the standard model prediction. Limits on WW gamma and WWZ anomalous couplings are presented. RI Vucinic, Dejan/C-2406-2008; Chiarelli, Giorgio/E-8953-2012; Azzi, Patrizia/H-5404-2012
