The source is available as a tar'ed and gzip'ed package, which extracts the files into a directory called samurai_v1.0. The compilation can be done by running the Install command. This will also compile the two packages for the evaluation of the scalar integrals: QCDLOOP and AVH-OLO. The code has been developed and tested under Ubuntu and Mac OSX, please report any compilation problems under other operating systems to the authors.
The distribution contains a dedicated directory with examples of calculations performed with SAMURAI. The examples could be used as a guide to understand the framework, as templates to generate the codes for other virtual processes or to design an interface with other tools.
1. Examples with integrands given as numerators of Feynman diagrams
2. Examples with integrands given as product of tree level amplitudes
A package for the evaluation of the scalar integrals needs to be linked to SAMURAI to get full numerical results. SAMURAI has been linked to the following two libraries:
