Running time: 5 ms to 10 s for integrals typically occurring in practical computations longer for higher rank tensor integrals. Unusual features: Includes rudimentary routines for tensor algebraic operations and for performing traces over Dirac gamma matrices. Restrictions: One-loop integrals are limited to those involving no more than three propagator factors.
Solution method: Passarino–Veltman reduction formula, Denner–Dittmaier reduction formulae, and two new reduction algorithms described in the manuscript. Nature of problem: Analytic calculation of one-loop integrals in relativistic quantum field theory for arbitrarily high-rank tensor integrals and any kinematic configuration of real-valued external invariants and internal masses. RAM: 10 MB, depending on size of computation Operating system: Windows, Mac OS X, Linux (or any system supporting Mathematica 8.0 or higher). Programming language: Mathematica (Wolfram Language).Ĭomputer: Any, which supports Mathematica. of bytes in distributed program, including test data, etc.: 1224562 of lines in distributed program, including test data, etc.: 63912
