报告摘要:

TheStandard Model, an effective theory describing known particles and interactions,has several unsolved problems. It is believed that there is an even morefundamental theory than the Standard Model, called new physics beyond theStandard Model. Thesearch for new physics is one of the main challenges of modern science. Precisemeasurements of flavor physics, particularly meson decays, are an essentialapproach to investigate new physics. Meson decays can be calculated with goodaccuracy within a framework of the Standard Model, and hence sensitivity to newphysics is excellent. In recent years, a number of experimental anomalies havebeen found by precision measurements. Interestingly, some of these anomalieshave been cross-checked by different experiments. Struggling to explain theanomalies by new physics is a task of particle phenomenology, and the StandardModel itself also has such a history. In this talk, I will present recentprogress with new physics interpretations of the flavor anomalies, also knownas lepton flavor universality violation. I will also argue future prospects offlavor physics, including our proposed methods to distinguish the new physicsmodels.
