報(bào)告內(nèi)容:
The tau lepton is the only known lepton massive enough to decay into hadrons. Besides serving as a clean laboratory for studying various low-energy aspects of the strong interactions, the hadronic tau decays may also allow us to explore CP-violating effects both within and beyond the SM. In this talk, I will discuss the CP asymmetries in tau -> K_S pi nu decays, which arise due to the CP violation in neutral kaon mixing within the SM. Within a generic effective field theory framework, I will then discuss the CP asymmetries induced by the beyond-the-SM four-fermion operators up to dimension-6. Interesting observations as well as the correlations among different observables will be presented. These studies are relevant to the Belle II experiment as well as the proposed Tera-Z and STCF facilities.
