Lifetime ratios of heavy hadrons revisited — •Bernhard Pfirrmann — Universität, Regensburg, Deutschland

We investigate higher order corrections to the Heavy Quark Expansion for inclusive quantities like the lifetime ratio of heavy hadrons. In order to match the precission that will be reached at the Tevatron and the LHC for decays of heavy hadrons like the B_s, B_c or the Lambda_b accurate and relieable theoretical estimates are mandatory.
