Abstract
We study the first sub-leading correction to the cusp anomalous dimension in the high spin expansion of finite twist operators in 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
