LoopTools is a package for evaluation of scalar and tensor one-loop integrals based on the FF package by G.J. van Oldenborgh. It features an easy Fortran, C++, and Mathematica interface to the scalar one-loop functions of FF and in addition provides the 2-, 3-, and 4-point tensor coefficient functions.
LoopTools has been published in Comput. Phys. Commun. 118 (1999) 153
[hep-ph/9807565].
FF has been published in Z. Phys. C46 (1990) 425
[scanned
version from KEK].
The new automatic installation script gets you started quickly and
easily.
The following files can be downloaded:
LoopTools-2.7.tar.gz [525 kB, MD5: f7826466a6f07310382f3336830740ef] (current version 2.7)
To compile the libraries you need f77 and gcc.
From Mathematica 7 on you must also have g++ (and libstdc++) installed for the
MathLink compile.
Installation notes for the impatient:
Attention g77 users: Do not compile LoopTools with optimization.
If you must turn on optimization for performance reasons, be sure to test
the results against the ones calculated with the unoptimized version.
Ubuntu users: Do not (= DO NOT) install fort77.
Install gfortran.
More detailed instructions are given in the manual which is contained in PostScript form in the LoopTools distribution. You can also obtain the manual here.
