Particle physics aims to develop a Theory of Everything by modeling matter and forces with fundamental particles. The current theory, the Standard Model, explains three of the four fundamental forces but has limitations, such as not accounting for gravity or neutrino masses. This thesis focuses on the Ds meson, a particle abundantly produced in hadron colliders, to study quark production and search for lepton flavor violations. The research includes experimental measurements and theoretical comparisons using the ATLAS detector at CERN.
