Physics topics and mandate

This Topical Group will address experimental and theoretical aspects concerning

• Mixing and CP violation in b decays
• Mixing and CP violation in c decays
• CKM constraints
• Rare b decays
• Rare c decays
• Tests of lepton flavor universality in charged-current decays
• Tests of lepton flavor universality in neutral-current decays
• Searches for processes that are forbidden in the Standard Model
• Determinations of relevant hadronic properties (lifetimes, branching fractions, hadronic matrix elements, scattering phase shifts, …)

The goal is to identify the priorities and challenges and establish a roadmap for the next decades, from ongoing and planned experiments to future colliders/facilities.
