Precision flavour physics provides one of the most sensitive indirect probes of physics beyond the Standard Model. While experimental measurements in heavy-flavour systems have reached unprecedented precision, their interpretation is increasingly limited by theoretical uncertainties associated with nonperturbative QCD dynamics, long-distance effects, and electromagnetic corrections.
With Run3 at the LHC concluding in 2026 and BelleII steadily taking data, it is timely to establish a coherent programme of theoretical developments. The workshop will provide an opportunity to discuss how theoretical progress can be aligned closely with experimental analyses and needs.
The workshop is structured around three core challenges: the consolidation of benchmark nonperturbative quantities and uncertainty budgets; the control of multi-hadron dynamics and non-local effects through the interplay of lattice and continuum methods; and the consistent treatment of sub-percent effects such as electromagnetic corrections and isospin breaking. The programme aims to identify theoretically robust and experimentally accessible observables and to define priorities for precision B physics.
