Singlemassscale diagrams: construction of a basis for the epsilonexpansion
Abstract
Exploring the idea of Broadhurst on the ``sixth root of unity'' we present an ansatz for construction of a basis of transcendental numbers for the epsilonexpansion of single mass scale diagrams with two particle massive cut. As example, several new two and threeloop master integrals are calculated.
