Abstract: We propose a closed expression for the three loop anomalous dimension of aclass of twist-3 operators built with gauge fields and covariant derivatives.To this aim, we solve the long-range Bethe Ansatz equations at finite spin andprovide a consistent analytical formula obtained assuming maximaltranscendentality violation as suggested by the known one-loop anomalousdimension. The final result reproduces the universal cusp anomalous dimensionand obeys recursion relations inspired by the principle of reciprocityinvariance.
