| Özet |
| 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√ s= 7 TeV with the CMS detector at the LHC, corresponds to an integrated luminosity of 5.0 fb− 1. The measured value of the sum of the inclusive WW and WZ cross sections is σ (pp→ 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.The gauge symmetry of the standard model (SM) fixes the triple gauge boson couplings that determine the selfinteractions of W and Z bosons. The pair production of vector gauge bosons allows a direct test of the electroweak sector of the SM [1]. Observation of anomalous triple gauge boson couplings would be an indication of physics beyond the SM. |
