Planar master integrals for four-loop form factors
arXiv:1903.06171 · doi:10.1007/JHEP05(2019)073
Abstract
We present the complete set of planar master integrals relevant to the calculation of three-point functions in four-loop massless Quantum Chromodynamics. Employing direct parametric integrations for a basis of finite integrals, we give analytic results for the Laurent expansion of conventional integrals in the parameter of dimensional regularization through to terms of weight eight.
