| 摘要: | 摘要： A measurement of W + W − 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 −1 . 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 γ and WWZ anomalous triple gauge-boson couplings are set.
