Automatic Integral Reduction for Higher Order Perturbative Calculations
C. Anastasiou, A. Lazopoulos
Abstract
We present a program for the reduction of large systems of integrals to master integrals. The algorithm was first proposed by Laporta; in this paper, we implement it in MAPLE. We also develop two new features which keep the size of intermediate expressions relatively small throughout the calculation. The program requires modest input information from the user and can be used for generic calculations in perturbation theory.
