Abstract

Particularly interesting processes to test the Standard Model are non-leptonic B⁰_s → D_s^± K^∓ transitions. As these decays occur via pure tree diagrams, they allow a theoretically clean determination of the angle γ of the unitarity triangle. Considering recent LHCb results, an intriguing picture arises, showing tension with the Standard Model. Utilising the available experimental data, we perform a theoretical analysis in order to shed more light on these puzzling patterns. Do these puzzles actually indicate footprints of New Physics?
