Analytic two-loop results for selfenergy- and vertex-type diagrams with one non-zero mass
J. Fleischer, A. V. Kotikov, O. L. Veretin
For a large class of two-loop selfenergy- and vertex-type diagrams with only one non-zero mass () and the vertices also with only one non-zero external momentum squared ()…
Two-loop QCD corrections of the massive fermion propagator
J. Fleischer, F. Jegerlehner, O. V. Tarasov +1
The off-shell two-loop correction to the massive quark propagator in an arbitrary covariant gauge is calculated and results for the bare and renormalized propagator are presented.…
Methods to calculate scalar two-loop vertex diagrams
J. Fleischer, M. Tentyukov
We present a review of the Bielefeld-Dubna activities on multiloop calculations.
Automation of Feynman Diagram Evaluation
M. Tentyukov, J. Fleischer
A C-program DIANA (DIagram ANAlyser) for the automation of Feynman diagram evaluations is presented.
