The non-planar contribution to the four-loop universal anomalous dimension in N=4 Supersymmetric Yang-Mills theory

Abstract: We present the result of a full direct component calculation for the non-planar contribution to the four-loop anomalous dimension of the Konishi operator in N =4 Supersymmetric Yang-Mills theory. The result contains only zeta(5) term and is proportional to zeta(5) contribution in the planar case, which comes purely from wrapping corrections. We have extended also our previous calculations for the leading transcendental contribution arXiv:0811.0607 on non-planar case and have found the same results up to a common factor. It allows us to suggest that the non-planar contribution to the four-loop universal anomalous dimension for the twist-2 operators with arbitrary Lorentz spin is proportional to $S_1^2(j) \zeta(5)$. This result gives unusual double-logarithmic asymptotic $\ln^2 j$ for large j.
