| contents | The first measurements of the inclusive and normalised differential cross sections for the production of single top quarks in association with a W boson in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are presented. The data used were recorded with the CMS detector at the LHC during 2022, and correspond to an integrated luminosity of 34.7 $\mathrm{fb}^{-1}$. The analysed events contain one muon and one electron in the final state. A cross section of $84.1\pm 2.1(\mathrm{stat})\,^{+9.8}_{-10.2}(\mathrm{syst})\pm 3.3(\mathrm{lumi})$ pb is obtained, consistent with the predictions of the standard model. For the differential measurements, a fiducial region is defined according to the detector acceptance. The resulting differential distributions are unfolded to particle level showing good agreement with the predictions at next-to-leading order in perturbative quantum chromodynamics. |
