A Feynman Diagram Analyser DIANA - Graphic Facilities
J. Fleischer, M. Tentyukov
New developments concerning the extension of the recently introduced Feynman diagram analyser DIANA are presented.
Two-loop self-energy master integrals on shell
J. Fleischer, M. Yu. Kalmykov, A. V. Kotikov
Analytic results for the complete set of two-loop self-energy master integrals on shell with one mass are calculated.
Non factorizable corrections to the process
J. Fleischer, F. Jegerlehner, M. Tentyukov +1
We evaluate non factorizable corrections to the process due to the virtual t-quark. All two-loop vertex diagrams with 's and charged ghosts 's are i…
Applications of the Large Mass Expansion
J. Fleischer, A. V. Kotikov, O. L. Veretin
The method of the large mass expansion (LME) is investigated for selfenergy and vertex functions in two-loop order. It has the technical advantage that in many cases the expansion…
Large Mass Expansion versus Small Momentum Expansion of Feynman Diagrams
J. Fleischer, M. Yu. Kalmykov, O. L. Veretin
The method of the large mass expansion (LME) has the technical advantage that two-loop integrals occur only as bubbles with large masses. In many cases only one large mass occurs.…
Multi-Loop Calculations in the Standard Model: Techniques and applications
J. Fleischer, M. Tentyukov, O. L. Veretin
We present a review of the Bielefeld-Dubna activities on the multiloop calculations. In the first part a C-program DIANA (DIagram ANAlyser) for the automation of Feynman diagram ev…
