Evaluating scattering amplitudes with pySecDec 1.6

High Energy Physics - Phenomenology 2023-11-02 v1

Abstract

pSecDec is a computer tool to evaluate Feynman integrals and their weighted sums (amplitudes) using the method of sector decomposition and numerical integration. The new release of pySecDec version 1.6 comes with a significant performance boost (3x-9x in common scenarios), and new features to make the evaluation and asymptotic expansion of amplitudes and integrals easier and faster. In this article we briefly review these features.
