Four-loop massless propagators: A numerical evaluation of all master integrals

Article ID Journal Published Year Pages File Type

Abstract

We present numerical results which are needed to evaluate all non-trivial master integrals for four-loop massless propagators, confirming the recent analytic results of Baikov and Chetyrkin (2010) [1] and evaluating an extra order in ε expansion for each master integral.
