Abstract

A measurement of WW production in pp collisions at \\sqrt{s} = 7~\mathrm{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. The WW candidates consist of two oppositely charged leptons, electrons or muons, accompanied by large missing transverse energy. The WW 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 WWγ and WWZ anomalous triple gauge-boson couplings are set.
