Among the unitarity cuts of massless 4-loop propagators two classes haveremained unknown until recently: 2-loop 3-particle cuts, and 1-loop 4-particlecuts. In this article we shall discuss the calculation that completes themaster integrals for these cuts: both the motivation and the methods (includingdimensional recurrence relations and direct integration at higher space-timedimensions).
