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