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.
