First measurements of vector boson scattering in W±W± and WZ production in all-leptonic final states at $$ sqrt{s}=13.6 $$ TeV Journal Article

Overview

; A; bstract; ; ; The production cross sections of W; ; ±; ; W; ; ±; ; and WZ boson pairs in association with two jets in proton-proton collisions are measured at; ; ; $$ sqrt{s}=13.6 $$; ; ; 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.;
