A novel method to compute one loop 4 point functions
Abstract
We present a part of an ongoing work initiated by Prof. Shimizu on a method to compute numerically two loop scalar integrals as a sum of two dimensional integrals of generalized scalar one loop four point functions. This implies to have a formula for the one loop scalar four point functions which is valid outside the physical domain, this is the object of the present work.
