The Heavy Flavor Averaging Group (HFLAV) was established at the May 2002 Flavor Physics and CP Violation Conference (Philadelphia) and continues the LEP Heavy Flavor Steering Group's tradition of providing regular updates to the world averages of heavy flavor quantities.

The latest averages can be found at Y. Amhis et al., Averages of b-hadron, c-hadron, and tau-lepton properties as of 2021, Phys. Rev. D107, 052008  , arXiv:2206.07501 and online updates here.

The activities of HFLAV are currently divided up into seven sub-groups that focus on individual measurements.

• b-hadron lifetimes and oscillation parameters
• Semi-leptonic B decays
• Rare B decays
• Unitarity triangle angles
• B decays to charm final states
• Charm CP violation and oscillations
• Charm decays
• Tau Physics
