Formationszeiteffekte in der Produktion von Charmonia in Proton-Kern Kollisionen
In dieser Arbeit wird die Absorption von Charmonia in Proton-Kern Stoessen bei Einschussenergien von mehreren hundert GeV behandelt. Formationszeiteffekte werden in einem Modell untersucht, das die zeitliche Entwicklung von Charmonia in Kernmaterie durch die zeitabhaengige Schroedingergleichung …

Radiative Transitions in Charmonium
… of radiative partial widths of exotic charmonia using dynamical quarks are calculated.

Weak decays of beautiful pseudoscalar mesons with Lattice Quantum Chromodynamics
… work on the long-distance contributions of charmonia on the flavour-changing neutral current process $B \to K$ is discussed. Difficulties with intermediate states that lead to divergences in the corresponding correlation function are addressed by again using the non-relativistic approach for …

Aspects of hadronic B decays in and beyond the standard model
… the context of QCD factorization, treating the charmonia as non-relativistic bound states. This allows us to demonstrate that, in the heavy-quark limit, a perturbative treatment of these decays is possible, even in case of decays into P-waves, which were found to be non-factorizing in previous …

Measurement of J/ψ meson production in association with a W [superscript ±] boson in pp data at 13 TeV collected by the ATLAS experiment
This dissertation presents a measurement of the production cross-section of J/ψ mesons in association with a W [superscript ±] boson in √s = 13 TeV pp collisions by the ATLAS experiment, using 139 fb⁻¹ of integrated luminosity produced by the Large Hadron Collider at CERN. Events are selected with …

Exotic charm resonances and coupled-channel scattering from lattice QCD
… but only weak and decoupled interactions in the charmonia-light channels. Finally, in Chapter 8, we summarise our work and finish with an outlook, where we suggest future work which will build upon the work done for this thesis and further our understanding of QCD.
