Abstract

A measurement of W$^+$W$^-$ production in pp collisions at $\sqrt{s}$ = 7 TeV is presented. The data were collected with the CMS detector at the LHC, and correspond to an integrated luminosity of 4.92 +/- 0.11 fb$^{-1}$ inverse femtobarns. The W$^+$W$^-$ candidates consist of two oppositely charged leptons, electrons or muons, accompanied by large missing transverse energy. The W$^+$W$^-$ production cross section is measured to be 52.4 +/- 2.0 (stat.) +/- 4.5 (syst.) +/- 1.2 (lum.) pb. This measurement is consistent with the standard model prediction of 47.0 +/- 2.0 pb at next-to-leading order. Stringent limits on the WW$\gamma$ and WWZ anomalous triple gauge-boson couplings are set.
