In this article we present a method to generate analytic expressions for the integral coefficients of loop amplitudes using numerical evaluations only. We use highprecision arithmetics to explore the singularity structure of the coefficients and deco... Read More about Extracting analytical one-loop amplitudes from numerical evaluations.
