The principle of maximal transcendentality and the four-loop collinear anomalous dimension

We use the principle of maximal transcendentality and the universal nature of subleading infrared poles to extract the analytic value of the four-loop collinear anomalous dimension in planar N = 4 super-Yang-Mills theory from recent QCD results, obtaining (G) over cap (0) ((4)) = -300 zeta(7) -256 zeta(2)zeta(5) -384 zeta(3)zeta(4). This value agrees with a previous numerical result to within 0.2%. It also provides the Regge trajectory, threshold soft anomalous dimension and rapidity anomalous dimension through four loops.
