Master Integrals for Four-Loop Massless Form Factors
arXiv:2309.00054
Abstract
We present analytical results for all master integrals for massless three-point functions, with one off-shell leg, at four loops. Our solutions were obtained using differential equations and direct integration techniques. We review the methods and provide additional details.
