Measurement of the inclusive WZ production cross section in pp collisions at $ \sqrt{s}= $ 13.6 TeV with the CMS experiment  
CMS Collaboration  
19 July 2024  
Abstract: The inclusive WZ cross section is measured in protonproton collisions at a centreofmass energy of 13.6 TeV, using 34.7 fb$ ^{1} $ of data collected during 2022 with the CMS detector. The measurement is performed in multileptonic final states by performing a simultaneous likelihood fit to the number of events in four different lepton flavour categories: $ \mathrm{eee} $, $ \mathrm{ee}{\mu} $, $ {\mu}{\mu}\mathrm{e} $, $ {\mu}{\mu}{\mu} $. The selection is optimized to minimize the number of background events thanks to the usage of an efficient prompt lepton discrimination strategy. The WZ production cross section is measured in a phase space, defined around a 30 GeV window around the Z mass, as $ \sigma_{\text{total}} (pp \rightarrow \mathrm{WZ}) = $ 55.2 $ \pm $ 1.2 (stat) $ \pm $ 1.2 (syst) $ \pm $ 0.8 (lumi) $ \pm $ 0.1 (theo) pb. In addition, the cross section is also measured in a fiducial phase space, closer to the detector level requirements, as $ \sigma_{\text{fiducial}} (pp \rightarrow \mathrm{WZ}) = $ 297.6 $ \pm $ 6.4 (stat) $ \pm $ 6.4 (syst) $ \pm $ 4.2 (lumi) $ \pm $ 0.5 (theo) pb.

Summary 
The $ \mathrm{pp}\to\mathrm{W}\mathrm{Z} $ production is studied in the trilepton final state at a new energy regime of $ \sqrt{s}= $ 13.6 TeV, using the 2022 data set with a total integrated luminosity of 34.7 fb$ ^{1} $. The production cross section in the total and fiducial phase spaces are measured in the inclusive case as well as up to four different combinations of final state flavour composition. The cross section is measured to be $ \sigma_{\text{total}}(\mathrm{p}\mathrm{p} \rightarrow \mathrm{W}\mathrm{Z}) = $ 55.2 $ \pm $ 1.2 (stat) $ \pm $ 1.4 (syst) $ \pm $ 0.1 (theo) pb. The observed accuracy that is achieved is shown to be competitive with previous measurements in terms of systematic uncertainty. This measurement is an addition to the set of LHC WZ cross section measurements, shown in Fig. 9, where the different results at different $ \sqrt{s} $ are also included.
