Towards Higgs boson production in gluon fusion to NNLO in the MSSM
Alexey Pak, Matthias Steinhauser, Nikolai Zerf
We consider the Higgs boson production in the gluon-fusion channel to next-to-next-to-leading order within the Minimal Supersymmetric Standard Model. In particular, we present anal…
Precise Charm- and Bottom-Quark Masses: Theoretical and Experimental Uncertainties
K. Chetyrkin, J. H. Kühn, A. Maier +4
Recent theoretical and experimental improvements in the determination of charm and bottom quark masses are discussed. A new and improved evaluation of the contribution from the glu…
The static quark potential to three loops in perturbation theory
Alexander V. Smirnov, Vladimir A. Smirnov, Matthias Steinhauser
The static potential constitutes a fundamental quantity of Quantum Chromodynamics. It has recently been evaluated to three-loop accuracy. In this contribution we provide details on…
Beyond Heavy Top Limit In Higgs Boson Production At LHC
Alexey Pak, Mikhail Rogal, Matthias Steinhauser
QCD corrections to inclusive Higgs boson production at the LHC are evaluated at next-to-next-to leading order. By performing asymptotic expansion of the cross section near the limi…
Large-m_c Asymptotic Behaviour of O(alpha_s^2) Corrections to B -> X_s gamma
Mikolaj Misiak, Matthias Steinhauser
We present details of our evaluation of the NNLO QCD corrections to BR(B -> X_s gamma) in the heavy charm limit m_c >> m_b/2. Results of this calculation have been essential for es…
Full result for the three-loop static quark potential
Alexander V. Smirnov, Vladimir A. Smirnov, Matthias Steinhauser
The three-loop corrections to the potential of two heavy quarks are computed. Analytic results for the most complicated master integrals are presented.
Three-loop vertex corrections
Matthias Steinhauser
We describe recent evaluations of three-loop vertex corrections which have been performed in the context of different physical applications: the massless quark and gluon form facto…
