| Measurement of W$^{+}$W$^{-} $ inclusive and differential cross sections in pp collisions at $ \sqrt{s}= $ 13.6 TeV with the CMS detector | ||
| CMS Collaboration | ||
| 24 March 2024 | ||
| Abstract: First measurements of the opposite-sign W boson pair production cross section in proton-proton collisions at $ \sqrt{s}= $ 13.6 TeV are presented. The data used in this study were collected with the CMS detector at the CERN LHC in 2022, and correspond to an integrated luminosity of 34.8 fb$ ^{-1} $. Events are selected by requiring one electron and one muon of opposite charges. A maximum likelihood fit is performed in event categories defined by the flavour and charge of the leptons, the number of jets, and number of jets identified as originating from b quarks. An inclusive $ \mathrm{W}^{+}\mathrm{W^{-}} $ production cross section of 125.7 $ \pm $ 5.6 pb is measured, in agreement with standard model predictions. Cross sections are also reported in a fiducial region close to that of the detector acceptance, both inclusively and differentially as a function of the jet multiplicity in the event. | ||
