3VIL is a library of utilities for the numerical evaluation of 3-loop vacuum basis integrals.
It implements analytical results where known, and otherwise evaluate the basis integrals using
Runge-Kutta integration of the coupled differential equations involving derivatives of the squared mass arguments.
The code is written in C, and may be linked from C or C++.
3VIL is free software, released under the
The authors are Stephen P. Martin and David G. Robertson. The paper announcing 3VIL, and containing the calculations on which it is based, is available from the arXiv.org preprint archive as 1610.07720.
The source code for the current version (v1.0, October 25, 2016) of the program can be downloaded here as a gzipped tar file: 3vil-v1.0.tar.gz. This unpacks into a single directory, which contains the C source files and a README.txt file with complete instructions for building and using 3VIL.
