Kira - Feynman Integral Reduction Program

Abstract:
In this talk, I present an alternative implementation of the Laporta algorithm used to reduce scalar multi-loop integrals - appearing in quantum field theoretic calculations - to a small set of master integrals, which will be soon made public. We (together with Philipp Maierhoefer and Peter Uwer) extend existing approaches by using integer based arithmetic to remove linearly dependent equations from the system of equations arising from integration by-parts and Lorentz identies. I describe in detail the implementation. In addition, I show benchmarks for concrete examples and compare the performance to Reduze. As a consequence of the aforementioned improvements, we find a significant increase in the performance.
