Manuscript Title: Package-X: A Mathematica package for the analytic calculation of one-loop integrals | ||

Authors: Hiren H. Patel | ||

Program title: Package-X | ||

Catalogue identifier: AEXT_v1_0Distribution format: tar.gz | ||

Journal reference: Comput. Phys. Commun. 197(2015)276 | ||

Programming language: Mathematica (Wolfram Language). | ||

Computer: Any, which supports Mathematica. | ||

Operating system: Windows, Mac OS X, Linux (or any system supporting Mathematica 8.0 or higher). | ||

RAM: 10 MB, depending on size of computation | ||

Keywords: One-loop, Feynman Integrals, Passarino-Veltman. | ||

Classification: 4.4, 11.1. | ||

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. | ||

Solution method:Passarino-Veltman reduction formula, Denner-Dittmaier reduction formulae, and two new reduction algorithms described in the manuscript. | ||

Restrictions:One-loop integrals are limited to those involving no more than three propagator factors. | ||

Unusual features:Includes rudimentary routines for tensor algebraic operations and for performing traces over Dirac gamma matrices. | ||

Running time:5ms to 10s for integrals typically occurring in practical computations; longer for higher rank tensor integrals. |
