dc.descriptionWe 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.
dc.descriptionLaTeX, 10 pages, 1 table; v2: sign changed in W_1 of Fig.1 and corresponding correction for the coeff. of zeta(3) in the final result, references added; v3: version published in Phys.Lett.B
