TTP03-10 Three-loop anomalous dimension of the heavy-light quark current in HQET
TTP03-10 Three-loop anomalous dimension of the heavy-light quark current in HQET
The anomalous dimension of the heavy-light quark current in HQET
is calculated with three-loop accuracy,
as well as the renormalized heavy-quark propagator.
The NNL perturbative correction to f_B/f_D is obtained.
