Interactions between elementary particles are well described by the Standard Model of particle physics. However, number of experiments observing discrepancies between theory and experiment gradually rises.
One of the most promising clues to new physics beyond Standard Model can be hidden in properties of B-mesons. This work relates to the angular analyses of the final-state particles of the rare Bd to KASTERISK OPERATOR (892) muon muon decay and of the decay of Bs to J/ψϕ with the ATLAS detector in Run 2.
