Automatized calculation of 2-fermion production with DIANA and aITALC
J. Fleischer, A. Lorca, T. Riemann
The family of two fermion final states is among the cleanest final states at the International Linear Collider (ILC) project. The package aITALC has been developed for a calculatio…
Status of Electroweak Corrections to Top Pair Production
J. Fleischer, A. Leike, T. Riemann +1
We review the status of electroweak radiative corrections to top-pair production at a Linear Collider well above the production threshold. We describe the Fortran package topfit an…
One-loop corrections to the process e+ e- -> t tbar including hard bremsstrahlung
J. Fleischer, J. Fujimoto, T. Ishikawa +4
Radiative corrections to the process e+ e- to t tbar are calculated in one-loop approximation of the Standard Model. There exist results from several groups. This talk provides fur…
Complete electroweak one-loop radiative corrections to top-pair production at TESLA -- a comparison
J. Fleischer, T. Hahn, W. Hollik +3
Electroweak one-loop radiative corrections to the process e^+ e^- -> t tbar are revisited. Two groups from Karlsruhe and Bielefeld/Zeuthen performed independent calculations of bot…
DIANA, a program for Feynman Diagram Evaluation
M. Tentyukov, J. Fleischer
A C-program DIANA (DIagram ANAlyser) for the automatic Feynman diagram evaluation is presented.
Techniques for Calculating two-loop Diagrams
J. Fleischer, O. L. Veretin
Methods developed by the Bielefeld-DESY-Dubna collaboration in recent years are: DIANA (DIagram ANAlyser), a program to produce ``FORM input'' for Feynman diagrams, starting from t…
