Exploring the Invisible Renormalon: Renormalization of the Heavy-Quark Kinetic Energy
Matthias Neubert
Using the virial theorem of the heavy-quark effective theory, we show that the mixing of the operator for the heavy-quark kinetic energy with the identity operator is forbidden at…
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…

QCD Sum-Rule Calculation of the Kinetic Energy and Chromo-Interaction of Heavy Quarks Inside Mesons
Matthias Neubert
We present a QCD sum-rule determination of the heavy-quark kinetic energy inside a heavy meson, , which is consistent with the field-theory analog of the virial theorem…
Asymptotics of Heavy-Meson Form Factors
Andrey G. Grozin, Matthias Neubert
Using methods developed for hard exclusive QCD processes, we calculate the asymptotic behaviour of heavy-meson form factors at large recoil. It is determined by the leading- and su…
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…
