Inside the precision era: exploring new physics through quark flavor transitions at LHCb

Abstract

The Standard Model (SM) is a quantum field theory that describes elementary particles and their interactions. While its predictions have been repeatedly confirmed by experiments, it cannot explain several phenomena such as dark matter and the matter-antimatter asymmetry. Therefore, new physics (NP) models are needed. This thesis explores these issues in three ways. First, the most accurate measurement of the CP-violation parameter φs, is achieved to test the SM. Second, advancements in the flavor tagging algorithm using the inclusive approach are analyzed to enhance future measurements. Finally, the implications of the latest flavor precision measurements in the context of supersymmetric models, which address some of the limitations of the SM, are reported in this thesis.
