Third party Tools

OpenLoops makes use of the following third-party tools which are shipped and compiled together with OpenLoops.

COLLIER

By default the COLLIER library by A. Denner, S. Dittmaier and L. Hofer is linked for the fast and numerically stable evaluation of one-loop tensor and scalar integrals. If used please cite
