Heavy-Quark Effective Theory
Matthias Neubert
We give an introduction to the heavy-quark effective theory and the expansion, which provide the modern framework for a systematic, model-independent description of the pro…

Measuring in Decays
Maria Girone, Matthias Neubert
The decay rate of the lepton into hadrons of invariant mass smaller than can be calculated in QCD using the OPE. Using experimental data on the hadronic mass…
A Fresh Look at the B Semileptonic Branching Ratio and Beauty Lifetimes
Matthias Neubert
We discuss two problems in the theory of heavy-quark decays: an understanding of the semileptonic branching ratio of mesons, and of the lifetime ratio . We also…
