The decay of the W boson to a muon and a muon-neutrino is studied. Proton-proton collisions at the LHC at √s= 13 TeV are the basis of the data taken in 2015-2018 with the ATLAS detector, corresponding to an integrated luminosity of 140 fb−1. Single-differential cross-sections as a function of the transverse mass, covering mTW ∈[200,5000] GeV, are presented. Additionally, double-differential cross-sections as a function of mTW and the pseudorapidity of the muon, covering mTW ∈[200,2000] GeV and |η(µ)|<2.4, are included. Both measurements are performed separately per W-boson charge, and their asymmetry is calculated as well.The number of signal events is unfolded to the Born level. Statistical and systematic uncertainties are included in the results. Overall, the total uncertainty ranges between ∼3 % and ∼65 % in the investigated spectra. Born-level theory predictions from simulations using Powheg+Pythia 8 and Sherpa 2.2.11, respectively, are compared to the unfolded cross-sections. Finally, a combination of the muon-channel measurement performed in this thesis and a parallel electron-channel measurement is presented.Johanna Wanda KrausBergische Universität Wuppertal, Dissertation, 2025Wuppertal539urn:nbn:de:hbz:468-2-547110.25926/BUW/0-82799375374387306441Measurement of the double-differential W -> µν cross-section at high transverse masses at √s= 13 TeV with the ATLAS detectorKraus, JohannaDruck-AusgabeHT030957055https://dx.doi.org/10.25926/BUW/0-827https://nbn-resolving.org/urn:nbn:de:hbz:468-2-5471Open AccessCC BY-NC-ND 4.02025-01-15oaDoctoralThesispublic25022420250410163544.0CT009000363s2w-hsswupubwgerUBW:C:C.02
