Seminar topic: “Anomalous dimension of the heavy-light quark current in HQET up to four loops”
Speaker: Andrey Grozin (Budker Institute of Nuclear Physics, Novosibirsk)
Abstract:
The anomalous dimension of the heavy-light quark current in HQET is calculated up to four loops. The N3LL perturbative correction to fB/fD is obtained.
