| 摘要: | 摘要： (ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) A measurement of the inclusive WW+WZ diboson production cross section in proton-proton collisions is reported, based on events containing a leptonically decaying W boson and exactly two jets. The data sample, collected at ... with the CMS detector at the LHC, corresponds to an integrated luminosity of 5.0 fb^sup -1^. The measured value of the sum of the inclusive WW and WZ cross sections is [sigma](pp[arrow right]WW+WZ)=68.9±8.7 (stat.)±9.7 (syst.)±1.5 (lum.) pb, consistent with the standard model prediction of 65.6±2.2 pb. This is the first measurement of WW+WZ production in pp collisions using this signature. No evidence for anomalous triple gauge couplings is found and upper limits are set on their magnitudes.
