FIRCLA, one-loop correction to e+ e- to nu anti-nu H and basis of Feynman integrals in higher dimensions
F. Jegerlehner, O. Tarasov
An approach for an effective computer evaluation of one-loop multi-leg diagrams is proposed. It's main feature is the combined use of several systems - DIANA, FORM and MAPLE. As an…
DIANA and selected applications
J. Fleischer, M. Tentyukov, O. V. Tarasov
New developments concerning the extension of the Feynman diagram analyzer DIANA are presented. We discuss new graphics facilities, different approaches to automation of momenta dis…
Massive two-loop Bhabha scattering -- the factorizable subset
J. Fleischer, T. Riemann, O. V. Tarasov +1
The experimental precision that will be reached at the next generation of colliders makes it indispensable to improve theoretical predictions significantly. Bhabha scattering (e^+…
Factorizing one-loop contributions to two-loop Bhabha scattering and automatization of Feynman diagram calculations
J. Fleischer, O. V. Tarasov, T. Riemann +1
In higher order calculations a number of new technical problems arise: one needs diagrams in arbitrary dimension in order to obtain their needed -expansion, zero Gram determinan…
