Special colloquium: What can we learn from charm?

Start: Location: CP-03-123
Carolina da Silva Bolognani will present the topic "What can we learn from charm?" on July 28.

Charm decays offer a unique window into the dynamics of up-type quark transitions, and therefore stand as an important testing ground for the Standard Model and potential new physics. In this talk, I will discuss charm decays via charged weak currents. First, from (semi)leptonic decays, I will present a new extraction of the V_cs CKM element, highlighting current tensions and examining the available space for new physics to manifest in c->s l nu transitions. Then, I will turn to the more complex domain of hadronic decays, where theoretical predictions are more challenging due to strong interaction effects. Using SU(3)_F symmetry of QCD, and accounting for its breaking, I will discuss two-body D-> eta’ {pi, K, eta} decays, presenting branching ratio predictions and prospects for CP violation. By the end of this talk, I hope to have convinced you that charm decays remain an essential area of study in flavour physics, and more experimental data is anxiously awaited!
