In this thesis, W+charm production is measured in proton-proton collisions at the LHC at 13 TeV, as recorded by the Compact Muon Solenoid (CMS) experiment. The analysis focuses on the identification of W bosons in their leptonic decay to a muon and a neutrino and charm quarks are tagged via the full reconstruction of D*-Mesons. The measured cross sections of W+c production are used, in combination with other relevant CMS results and the most precise HERA DIS data, in a QCD analysis to determine the strange quark content of the proton. The resulting strange quark distribution and suppression, with respect to the other light sea quarks, are in good agreement with those obtained in neutrino scattering experiments and extend their kinematic reach.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Elementary particles (Physics)Quantum field theoryNuclear physicsElementary Particles, Quantum Field Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P23029Particle and Nuclear Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P23002Elementary particles (Physics).Quantum field theory.Nuclear physics.Elementary Particles, Quantum Field Theory.Particle and Nuclear Physics.539.72167Pflitsch Svenja Karenauthttp://id.loc.gov/vocabulary/relators/aut841746MiAaPQMiAaPQMiAaPQBOOK9910427691503321Associated Production of W + Charm in 13 TeV Proton-Proton Collisions Measured with CMS and Determination of the Strange Quark Content of the Proton1878929UNINA
