Completely automated computation of the heavy-fermion corrections to the three-loop matching coefficient of the vector current
P. Marquard, J. H. Piclum, D. Seidel +1
We evaluate the corrections to the matching coefficient of the vector current between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) to three-loop order containing a…
Semileptonic decays in the limit of a heavy daughter quark
Matthew Dowling, Jan H. Piclum, Andrzej Czarnecki
The rate of the semileptonic decay b to c l v is calculated with order alphas^2 accuracy, as an expansion around the limit of equal masses of the b and c quarks. Recent results obt…
Three-Loop Chromomagnetic Interaction in HQET
A. G. Grozin, P. Marquard, J. H. Piclum +1
We compute the three-loop QCD corrections to the quark chromomagnetic moment and thus obtain the matching coefficient and the anomalous dimension of the chromomagnetic interaction…
Relation between the pole and the minimally subtracted mass in dimensional regularization and dimensional reduction to three-loop order
P. Marquard, L. Mihaila, J. H. Piclum +1
We compute the relation between the pole quark mass and the minimally subtracted quark mass in the framework of QCD applying dimensional reduction as a regularization scheme. Speci…
Fermionic Corrections to the Three-Loop Matching Coefficient of the Vector Current
P. Marquard, J. H. Piclum, D. Seidel +1
In this paper we consider the matching coefficient of the vector current between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) to three-loop order in perturbation t…
Two-Loop Matching Coefficients for Heavy Quark Currents
B. A. Kniehl, A. Onishchenko, J. H. Piclum +1
In this paper we consider the matching coefficients up to two loops between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) for the vector, axial-vector, scalar and p…
