Matching QCD and HQET heavy-light currents at three loops
S. Bekavac, A. G. Grozin, P. Marquard +3
We consider the currents formed by a heavy and a light quark within Quantum Chromodynamics and compute the matching to Heavy Quark Effective Theory to three-loop accuracy. As an ap…
Gluinonia: Energy Levels, Production and Decay
Matthias R. Kauth, Johann H. Kuhn, Peter Marquard +1
Predictions for energy levels, production and decay rate of gluinonia, non-relativistic boundstates of gluinos, are presented. The potential between color-octet constituents is der…
Reconstruction of heavy quark current correlators at O(α_s^3)
Y. Kiyo, A. Maier, P. Maierhoefer +1
We construct approximate formulas for the O(α_s^3) QCD contributions to vector, axial-vector, scalar and pseudo-scalar quark current correlators, which are valid for arbitrary valu…
Low energy moments of heavy quark current correlators at four loops
A. Maier, P. Maierhoefer, P. Marquard +1
We describe several techniques for the calculation of multi-loop integrals and their application to heavy quark current correlators. As new results, we present the four-loop correc…
Charm and Bottom Quark Masses: an Update
K. G. Chetyrkin, J. H. Kuhn, A. Maier +4
Using new four-loop results for the heavy quark vacuum polarization and new data for bottom quark production in electron-positron annihilation, an update on the determination of ch…
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…
