Automatic Computation of Feynman Diagrams
R. Harlander, M. Steinhauser
Quantum corrections significantly influence the quantities observed in modern particle physics. The corresponding theoretical computations are usually quite lengthy which makes the…
Completely Automated Calculations of Multi-Loop Diagrams
M. Steinhauser
The computation of higher order processes very often involves a large number of diagrams. In addition, it is in general not possible to solve the occurring integrals explicitly and…
Higgs Decay into Gluons up to O(α_s^3 G_F m_t^2)
Matthias Steinhauser
The decay of the Standard Model Higgs boson in the intermediate-mass range into gluons is considered where special emphasis is put on the influence of the leading electroweak corre…
Leptonic contribution to the effective electromagnetic coupling constant up to three loops
M. Steinhauser
In this note the leptonic contribution to the running of the electromagnetic coupling constant is discussed up to the three-loop level. Special emphasize is put on the evaluation o…
A theory driven analysis of the effective QED coupling at
J. H. Kühn, M. Steinhauser
An evaluation of the effective QED coupling at the scale M_Z is presented. It employs the predictions of perturbative QCD for the cross section of electron positron annihilation in…
