The Heavy Flavor Averaging Group

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 summer 2016Eur. Phys. J. C77 (2017) 895arXiv:1612.07233 and online updates here.

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