Two-loop Six-point Planar Massless Feynman Integrals to Higher Orders
Yuanche Liu, Antonela Matijašić, Tiziano Peraro +3
In this work, we calculate two-loop six-point planar massless Feynman integrals at higher orders in the dimensional regulator , corresponding to higher transcendental weights. I…
