The Theoretical Phenomenology Visiting Institute@LNF will host a two-day workshop titled ‘The Semileptonic B Frontier: LHC, B-factories, Lattice QCD & the Hunt for Precision’ from February” 16 to 18, 2026, as part of its activities scheduled for February 16–20.

The aim of the workshop is to bring together theorists and experimentalists working on various aspects of semileptonic b-hadron decays for both charged and neutral flavour changing current processes. Topics will include recent developments, open questions, and future directions, including novel lattice approaches for inclusive B decays, CKM determinations, hadronic form factors, and potential signals of New Physics.

Participants will review the latest B-physics experimental results and the theoretical inputs, will discuss new observables and tools to enhance the future analyses. The aim of the workshop is to foster the collaboration across different communities, to improve the understanding of experimental systematic uncertainties and theoretical calculations in this crucial area of flavor physics.
