We develop a new bootstrap method and compute for the first time a two-loop four-point form factor in N = 4 SYM, which belongs to the non-trivial class of two-loop 2->3 scattering amplitudes with one external leg being off-shell.

We address the next-to-leading power (NLP) resummation of large double logarithms of 1 − x to all orders in the strong coupling, which are present even in the off-diagonal DGLAP splitting kernels. The appearance of divergent convolutions prevents the application of factorization methods known from leading power resummation. Employing d-dimensional consistency relations from requiring 1/ε pole...
