Description
After recalling the basics of generalized unitarity and maximal cuts, I will discuss recent work with Mads S{\o}gaard and Yang Zhang (1704.04255):
We discuss a procedure for computing maximal cuts in general D dimensions, based on the Baikov representation which simplifies the structure of the cuts. In our procedure, for a given topology, the integration splits into several regions and the number of independent regions is equal to the number of master integrals for the topology. The functions thus obtained inherit IBP and dimension shift identities from the uncut integral. Moreover, the functions, corresponding to the master integrals, obtained from the different regions, form the Wronskian matrix for the system of differential equations on the maximal cut. The discussion will be guided by an explicit example (probably the massless double box, but this remains to be decided).
