Özet
Measurements of production cross sections of W Z and same-sign W W boson pairs in association with two jets in proton-proton collisions at s= 13 TeV at the LHC are reported. The data sample corresponds to an integrated luminosity of 137 fb− 1, collected with the CMS detector during 2016–2018. The measurements are performed in the leptonic decay modes Image 1 and Image 2, where ℓ, ℓ′= e, Image 3. Differential fiducial cross sections as functions of the invariant masses of the jet and charged lepton pairs, as well as of the leading-lepton transverse momentum, are measured for W±W±production and are consistent with the standard model predictions. The dependence of differential cross sections on the invariant mass of the jet pair is also measured for W Z production. An observation of electroweak production of W Z boson pairs is reported with an observed (expected) significance of 6.8 (5.3) standard …
