Anomalous dimension of the heavy-light quark current in HQET up to four loops
Andrey Grozin
The anomalous dimension of the heavy-light quark current in HQET is calculated up to four loops. The NLL perturbative correction to is obtained.
QCD cusp anomalous dimension: current status
Andrey Grozin
Calculation results for the HQET field anomalous dimension and the QCD cusp anomalous dimension, as well as their properties, are reviewed. The HQET field anomalous dimension …
Four-loop QCD cusp anomalous dimension at small angle
Andrey G. Grozin, Roman N. Lee, Andrey F. Pikelner
We calculate the small angle expansion of the four-loop QCD cusp anomalous dimension. As a byproduct of our calculation, we also obtain the four-loop anomalous dimension of the hea…
Correlators of heavy-light quark currents in HQET: OPE at three loops
K. G. Chetyrkin, A. G. Grozin
Coefficient functions of the operator product expansion of correlators of HQET heavy--light quark currents are calculated up operators of dimension 4 up to to 3 loops.
HQET vertex diagram: expansion
A. G. Grozin
Differential equations for the one-loop HQET vertex diagram with arbitrary self-energy insertions and arbitrary residual energies are reduced to the form and used to…
Matching the heavy-quark fields in QCD and HQET at four loops
Andrey G. Grozin, Peter Marquard, Alexander V. Smirnov +2
The QCD/HQET matching coefficient for the heavy-quark field is calculated up to four loops. It must be finite; this requirement produces analytical results for some terms in the fo…
