A C-program DIANA (DIagram ANAlyser) for the automation of Feynman diagram evaluations is presented. Recent high precision experiments require, on the side of the theory, high-precision calculations resulting in the evaluation of higher loop diagrams in the Standart Model (SM). For specific processes thousands of multiloop Feynman diagrams do contribute,… (More)

New developments concerning the extension of the recently introduced (1) Feynman diagram analyser DIANA are presented. Recent high precision experiments require, on the side of the theory, high-precision calculations resulting in the evaluation of higher loop diagrams in the Standard Model. For specific processes thousands of multiloop Feynman diagrams do… (More)

A method to calculate two-loop self-energy diagrams of the Standard Model is demonstrated. A direct physical application is the calculation of the two-loop electroweak contribution to the anomalous magnetic moment of the muon 1 2 (g − 2) µ. Presently we confine ourselves to a " toy " model with only µ, γ and a scalar particle (Higgs). The algorithm is… (More)

A direct physical application is the calculation of the two-loop electroweak contribution to the anomalous magnetic moment of the muon 1 2 (g − 2) µ. Presently, we confine ourselves to a " toy " model with only µ, γ and a heavy neutral scalar particle (Higgs). The… (More)

Details of recent developments of the Feynman diagram analyzer DIANA (DIagram ANAlyser) are presented. Apart from some discussion about QGRAF and new plotting features, we concentrate on a new sophisticated mechanism of momenta mapping. The C-program DIANA (DIagram ANAlyser) for the automatic Feynman diagram evaluation was first documented in [1] 1.… (More)

We present numerical results which are needed to evaluate all non-trivial master integrals for four-loop massless propagators, confirming the recent analytic results of [1] and evaluating an extra order in ε expansion for each master integral.

A C-program DIANA (DIagram ANAlyser) for the automatic Feynman diagram evaluation is presented. It consists of two parts: the analyzer of diagrams and the interpreter of a special text manipulating language. This language is used to create a source code for analytical or numerical evaluations and to keep the control of the process in general.
