Decoupling of heavy-quark loops in light-light and heavy-light quark currents

摘要

Matching of light-light quark currents in QCD with a heavy flavour and in the low-energy effective QCD is calculated in <(MS)over bar> at two loops. Heavy-light HQET currents are similarly considered. (C) 1998 Elsevier Science B.V. All rights reserved. [References: 13]
