TSIL is a library of utilities for the numerical calculation of dimensionally regularized two-loop self-energy integrals. It is written in C, and can be linked to C/C++ and Fortran applications. The authors are Stephen P. Martin and David G. Robertson. TSIL is free software, released under the GPL. The paper announcing and describing TSIL can be downloaded from the hep-ph preprint archive as hep-ph/0501132. The source code for the current version (v1.1, November 1, 2006) of the program can be downloaded here either in uuencoded form: tsil-1.1.uu, or as a gzipped tar file: tsil-1.1.tar.gz. These unpack into a single directory, which contains the C source files and a README.txt file with complete instructions for building and using TSIL. If you would like to be added to a mailing list for periodic information on updates to TSIL, please email drobertson (at) otterbein.edu.

In the Hopi culture indigenous to the American southwest, Tsil is the Chili Pepper Kachina, one of many supernatural spirits represented by masked doll-like figurines and impersonated by ceremonial dancers. Tsil is one of the runner Kachinas. When he overtakes you in a race, he may stuff your mouth with hot chili peppers.
