Conformal Integrals in four dimensions

High Energy Physics - Theory 2022-08-29 v2 Algebraic Geometry

Abstract

We obtain analytic expressions of four-dimensional Euclidean NN-point conformal integrals for arbitrary NN by solving a Lauricella-like system of differential equations derived earlier. We demonstrate their relation to the GKZ A-hypergeometric systems. The conformal integrals are solutions to these expressed in terms of leg factors and infinite series in the conformal invariant cross ratios.
