New results on purely leptonic decays of B hadrons from the Tevatron and B factories are also presented.9 pages, 11 figures, to appear in the Proceedings of Flavor Physics and CP Violation Workshop 2006 (FPCP 2006), add references, minor text changes, boldmathHigh Energy Physics - ExperimentHigh Energy Physics - Phenomenologytext
