A Novel Approach To Integration By Parts Reduction
Robert Schabinger (MITP, PRISMA)

Integration by parts reduction is a standard component of most modern multi-loop calculations in quantum field theory.
We present a novel integration by parts reduction strategy constructed to overcome limitations of currently available reduction programs based on Laporta`s algorithm. As a specific feature, the method allows for the effective usage of large computer clusters.
Our expectation is that the method will facilitate the evaluation of previously inaccessible higher-order corrections by simultaneously improving both the run-time and the memory requirements of the reduction procedure.
