We propose a new, infrared safe definition of heavy-quark jets which allows one to reduce theoretical uncertainties by a factor of three.4 pages, 4 figures, talk given at 42nd Rencontres de Moriond on QCD and High-Energy Hadronic Interactions, La Thuile, March 2007 and at the 15th International Workshop on Deep-Inelastic Scattering and related subjects, Munich, April 2007High Energy Physics - Phenomenologytext
