Anomalous dimensions of finite size field strength operators in N=4 SYM

Understand

In the N=4 super Yang-Mills theory, we consider the higher order anomalous dimensions gamma_L(g) of purely gluonic operators Tr(F^L) where 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.
