چکیده

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 contribute. Of course, the contribution of most of these diagrams is very small. But sometimes it is not so easy to distinguish between important and unimportant diagrams. On the other hand, we of

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. Meanwhile there exists a growing series of ap...
