Two-Loop Master Integrals for Leading-Color pp→ttH Amplitudes with a Light-Quark Loop*

In this talk we present the first calculation of two-loop Feynman integrals related to the production of a top-quark pair in association with a Higgs boson at the LHC. These integrals are a necessary ingredient for the computation of the associated NNLO QCD corrections. We construct a basis of master integrals satisfying an ϵ-factorized differential equation, and provide the differential equation in terms of a minimal set of differential one-forms. Furthermore, we explore the function space of iterated integral solutions of these differential equations. Finally, we make use of generalized series expasions to numerically integrate the differential equations from boundary conditions computed via auxiliary mass flow.
