Abstract
We present the planar four-loop anomalous dimension of the composite operator tr(Ï[Z,Ï]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 ζ(5) increasing the level of transcendentality of the anomalous dimension. In a sequel of this Letter all the details of our calculation will be reported.
