===== 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.
