Taming hadronic uncertainties in and beyond the Standard Model

22 oct. 2025, 12:50 → 24 oct. 2025, 15:00 Europe/Paris

100/-1-A900 - Auditorium Joliot Curie (IJCLab)

Hadronic form factors remain one of the primary sources of uncertainty in flavour observables. This workshop aims to bring together the lattice, phenomenological and experimental communities to discuss the latest improvements in the calculation, description and use of these form factors. The discussed topics will cover:

• New parametrisations based on analyticity;
• Progresses in the description of B -> 2 mesons form factors;
• Extraction of form factors from the data;
• Radiative decays;
• ...
