Title: Discovering New Physics with Flavour
Date: Thursday, Nov. 28th, 2019, 17:00-18:00

Venue: ES635


In the last years very intriguing hints for New Physics (NP) in the
flavour sector have been accumulated. In particular, deviations from
the Standard Model predictions in semi-leptonic B decays were
discovered, pointing strongly towards the violating of lepton flavour
universality (LFU). These hints for NP could be related to the long
standing discrepancy in the anomalous magnetic moment of the muon
which also measures LFU violation. Furthermore, there are interesting
tensions in direct CP violating observables in meson decays, i.e.
epsilon’/epsilon and B->Kpi. Even though these observables are not
directly related to LFU violation, they could be correlated in a UV
complete model. After reviewing the current experimental und
theoretical situation, I will discuss possible NP models which can
explain the anomalies. As it turns out, leptoquarks are prime
candidates for such an explanation und I will present some interesting
UV completions, including one based on the famous Pati-Salam gauge


The seminar is being held jointly by Tau-lepton center and KMI.
