Virtual three-loop corrections to Higgs boson production in gluon fusion for finite top quark mass
Alexey Pak, Mikhail Rogal, Matthias Steinhauser
In this letter we present the three-loop virtual corrections to the Higgs boson production in the gluon fusion channel where finite top quark mass effects are taken into account. W…
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…
Quark and gluon form factors to three loops
P. A. Baikov, K. G. Chetyrkin, A. V. Smirnov +2
We compute the form factors of the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons to three-loop order within massless perturbative Quantum…
corrections to the vertex at the top quark threshold
Yuichiro Kiyo, Dirk Seidel, Matthias Steinhauser
We compute the last missing piece of the two-loop corrections to vertex at the threshold due to the exchange of a boson and a gluon. T…
Loops for ILC
Matthias Steinhauser
This contribution summarizes the on-going activities connected to the evaluation of higher order radiative corrections in the context of a future international linear collider (ILC…
Precise quark masses from sum rules
Matthias Steinhauser
In this contribution an improved analysis is described to extract precise charm and bottom quark masses from experimental and theoretical moments of the photon polarization functio…
