Averages of b-hadron, c-hadron, and tau-lepton Properties

Abstract

This article reports world averages for measurements of b-hadron, c-hadron, and tau-lepton properties obtained by the Heavy Flavor Averaging Group (HFAG) using results available at least through the end of 2009. Some of the world averages presented use data available through the spring of 2010. For the averaging, common input parameters used in the various analyses are adjusted (rescaled) to common values, and known correlations are taken into account. The averages include branching fractions, lifetimes, neutral meson mixing parameters, CP violation parameters, and parameters of semileptonic decays.

version 3: 288 pages, 167 tables, 86 figures, updated b-hadron production fractions, A_sl in Bs decays, and tau chapter results
