1. What can flavour tell us about Dark Matter?

The non-trivial flavour structure of t-channel dark matter models with fermion couplings is unavoidably constrained by flavour physics, hinting towards the presence of an underlying flavour symmetry.
In this talk, I present a systematic study of the low-energy flavour constraints affecting these models from the perspective of flavour symmetries, together with complementary bounds from...

11. Implications of Flavor Symmetries for Baryon Number Violation

In the Standard Model, baryon number is an accidental symmetry, whose violation would constitute unambiguous evidence of new physics, with proton decay providing its most prominent experimental signature. At the same time, the peculiar structure of flavor can serve as a guiding principle for exploring possible new-physics effects. In this talk, I present a systematic classification of...

55. Pion $\beta$ decay and $\tau \rightarrow \pi \, \pi \, \nu_{\tau}$ beyond leading logarithms

Nicola Valori - (University of Valencia & IFIC)

09/06/2026, 15:40

Semi-leptonic processes involving pions are used to test the Standard Model at high precision. On the theory side, the evaluation of radiative corrections is a crucial ingredient for a robust comparison between theoretical predictions and experimental measurements. In this talk, I will present the first complete effective field theory treatment of radiative corrections in pion $\beta$ decay...
