The associated production of a W boson and a single charm quark (W+c) is the only process in proton-proton collisions that directly probes the strange quark content of the proton. 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.

Heavy Flavors covers the proceedings of the Third Topical Seminar on Heavy Flavors, held in San Miniato, Italy on June 17-21, 1991. The book focuses on the reactions, properties, characteristics, and transformations of heavy flavors. The publication first offers information on flavor factories and monochromatization as the way to maximum luminosity B-factories, as well as design strategies and parameters, requirements, luminosity limitations, and B-factory with monochromatization and vertical separation. The book then ponders on theoretical results in heavy quark hadroproduction; heavy flavor production at high energies; and leptonic decay constants of heavy mesons. The book examines heavy baryon transitions and the heavy quark effective theory; non universality of nucleon sea distributions probed by neutrinos and muons; and heavy flavor physics at hadron colliders. The publication is a dependable reference for readers interested in the study of heavy flavors.

This volume is a collection of review articles on the most outstanding topics in heavy flavour physics. All the authors have made significant contributions to this field. The book reviews in detail the theoretical structure of heavy flavour physics within the Standard Model and its confrontation with existing experimental data.The physics of the top quark and of the Higgs play an important role in this volume. Beginning with radiative electroweak corrections and their impressive tests at LEP and hadron colliders, the book summarizes the present status of quark mixing, CP violation and rare decays. The dynamics of exclusive D- and B-meson decays, the τ-lepton physics and the newly discovered heavy quark symmetries are discussed in detail. The impact of strong interactions on weak decays is clearly visible in many articles. The physics of heavy flavours at LEP, HERA and hadron colliders constitutes an important part of the book. Another significant topic is the possible role of heavy flavours in the spontaneous symmetry breaking of gauge symmetries. Finally the most recent advances in lattice calculations of the properties of heavy flavours and the lattice studies of the dynamics of heavy flavours are presented.
