Colloquium (Emilie Passemar): Tau decays: Status and Prospects at Belle II

Event Details

Speaker: Prof. Emilie Passemar (Indiana University)

Place: Natural Sciences Building, Room 112 

Several experimental collaborations have recently invested considerable effort in precision studies of tau decays. With Belle II in operation Tau lepton physics has now entered a new era of precision. It is therefore timely to discuss the theoretical implications of these experimental advances. In this talk, I will review several such implications. 

Firstly, I will discuss how studying the decays of the Tau lepton represents a very interesting laboratory to test weak interactions and fundamental symmetries. In particular, I will discuss how Tau physics could play a crucial role in resolving the Cabibbo anomaly puzzle. Then I will present the prospects Tau physics offers in looking for lepton flavour violation and constraining new dynamics. Finally, I will review the status of the Standard Model prediction of the anomalous magnetic moment of the muon and how hadronic tau decay data could affect it.
