====== TTP98-36 Decoupling of heavy-quark loops in light-light and heavy-light quark currents ====== Matching of light-light quark currents in QCD with a heavy flavour and in the low-energy effective QCD is calculated in MSbar at two loops. Heavy-light HQET currents are similarly considered. |**A.G.Grozin** | |** Phys. Lett.
