Abstract

In the Script N = 4 super Yang-Mills theory, we consider the higher order anomalous dimensions γL(g) of purely gluonic operators Tr Script FL where Script F is a component of the self-dual field strength. We propose compact closed expressions depending parametrically on L that reproduce the prediction of Bethe Ansatz equations up to five loop order, including transcendental dressing corrections. The size dependence follows a simple pattern as the perturbative order is increased and suggests hidden relations for these special operators.
