Four-loop beta function and mass anomalous dimension in Dimensional Reduction
R. V. Harlander, D. R. T. Jones, P. Kant +2
Within the framework of QCD we compute renormalization constants for the strong coupling and the quark masses to four-loop order. We apply the DR-bar scheme and put special emphasi…
NNLO QCD corrections to the B -> X_s gamma matrix elements using interpolation in m_c
Mikolaj Misiak, Matthias Steinhauser
One of the most troublesome contributions to the NNLO QCD corrections to B -> X_s gamma originates from three-loop matrix elements of four-quark operators. A part of this contribut…
Estimate of BR(B -> X_s gamma) at O(alpha_s^2)
M. Misiak, H. M. Asatrian, K. Bieri +14
Combining our results for various O(alpha_s^2) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next…
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…
Complete Higgs mass dependence of top quark pair threshold production to order
D. Eiras, M. Steinhauser
In this paper we consider the production of top quark pairs close to threshold and compute the dependence on the Higgs boson mass to order . This requires the evaluation of t…
