Description
We present the fully analytic result of the three-loop four-point correlator of stress tensor multiplets in N=4 SYM. We discuss the role played by single-valued versions of multiple polylogarithms and leading singularities of Feynman integrals in this construction. Finally, we give some first ideas about extending the technique to the four-loop correlator.
