Wrapping at four loops in N=4 SYM / F. Fiamberti, A. Santambrogio, C. Sieg, D. Zanon. - In: PHYSICS LETTERS. SECTION B. - ISSN 0370-2693. - 666:1(2008 Aug), pp. 100-105.
Abstract:
We present the planar four-loop anomalous dimension of the composite operator tr(phi[Z,phi]Z) in the flavour SU(2) sector of the N=4 SYM theory. At this loop order wrapping interactions are present: they give rise to contributions proportional to zeta(5) increasing the level of transcendentality of the anomalous dimension. In a sequel of this paper all the details of our calculation will be reported.
