"Integrability and multiple zeta-functions in planar N=4 SYM"

Abstract:

I will explain how to perform higher loop computations in planar N=4 SYM using integrability techniques. In particular, we will discuss the so called Konishi anomalous dimension, which we computed explicitly up to eight loops, observing appearance of a non-reducible multiple zeta-value for the first time, and for which the highest transcendental terms can be resummed at all orders of the perturbation theory. Finally, I will give a conjecture that only multiple zeta-values can appear in the answer at any order of the perturbative expansion.
