# Beyond cusp anomalous dimension from integrability in SYM{sub 4}

## Abstract

We study the first sub-leading correction O((ln s){sup 0}) to the cusp anomalous dimension in the high spin expansion of finite twist operators in N = 4 SYM theory. This term is still governed by a linear integral equation which we study in the weak and strong coupling regimes. In the strong coupling regime we find agreement with the string theory computations.
