Abstract

The production cross sections of W^±W^± and WZ boson pairs in association with two jets in proton-proton collisions are measured at √(s) = 13.6 TeV. The data sample corresponds to an integrated luminosity of 171 fb^-1, collected with the CMS detector during 2022-2024. The measurements are performed in the leptonic decay modes: W^±Z → ℓ^±νℓ^′±ℓ^′∓ and W^±W^± → ℓ^±νℓ^′±ν, where ℓ, ℓ' = e or μ. The electroweak productions of W^±W^± and WZ bosons are each observed with a significance greater than five standard deviations from the background-only hypothesis. Differential fiducial cross sections as functions of several observables are also measured.
