Description
The quark-flavour sector remains one of the most promising avenues for uncovering physics beyond the Standard Model, with an experimental programme set to sharpen its precision, and extend the set of measured quantities, well into the 2040s. Matching this requires lattice QCD to tackle existing and new formal challenges, and to work in ever-closer partnership with experiment.
I will survey these developments, before turning to the determination of key CKM matrix elements, where longstanding puzzles continue to challenge our understanding. I will also take a look at other new developments such as long-distance contributions to rare decay processes, where lattice methods are beginning to bring first-principles control to amplitudes once left to model-dependent estimates.
