A new Method for computing One-Loop Integrals
Lars Brucher, Johannes Franzkowski
We present a new program package for calculating one-loop Feynman integrals, based on a new method avoiding Feynman parametrization and the contraction due to Passarino and Veltman…
XLOOPS -- A Program Package calculating One- and Two-Loop Feynman Diagrams
L. Brücher, J. Franzkowski, D. Kreimer
The aim of XLOOPS is to calculate one-particle irreducible Feynman diagrams with one or two closed loops for arbitrary processes in the Standard model of particles and related theo…
oneloop 2.0 -- A Program Package calculating One-Loop Integrals
L. Brücher, J. Franzkowski, D. Kreimer
We present an improved version of our program package oneloop which -- written as a package for MAPLE -- solves one-loop Feynman integrals. The package is calculating one-, two- an…
Introduction to XLOOPS
L. Brücher, J. Franzkowski, A. Frink +1
The program package XLOOPS calculates massive one- and two-loop Feynman diagrams. It consists of five parts: i) a graphical user interface ii) routines for generating diagrams from…
Loop Integrals, R Functions and their Analytic Continuation
L. Bruecher, J. Franzkowski, D. Kreimer
To entirely determine the resulting functions of one-loop integrals it is necessary to find the correct analytic continuation to all relevant kinematical regions. We argue that thi…
