摘要：
We study maximal helicity three gaugino operators in N = 4 Super Yang-Mills theory. We show that the lowest anomalous dimension of scaling operators with generic finite spin can be expressed in terms of the universal anomalous dimension appearing at twist-2. This statement is rigourously proved at three loops. There as on forth is universality between sectors with different twist is the hidden psu(1 vertical bar 1) invariance of the su(2 vertical bar 1) subsector of the theory.
