Heavy Flavor Averaging Group Home Page

The Heavy Flavor Averaging Group (HFAG) 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 early 2012," arXiv:1207.1158
and online update at http://www.slac.stanford.edu/xorg/hfag

This group is currently organized into seven sub-groups that focus on a different set of heavy flavor measurements:

B lifetimes and oscillation parameters,
Semi-leptonic B decays,
Rare B decays,
Unitarity triangle parameters,
B decays to charm final states,
Charm Physics,
Tau Physics.
