(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) A measurement of W^sup +^W^sup -^ production in pp collisions at ... 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^sup -1^. The W^sup +^W^sup -^ candidates consist of two oppositely charged leptons, electrons or muons, accompanied by large missing transverse energy. The W^sup +^W^sup -^ 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.
