Bianchi, L., Forini, V. ORCID: 0000-0001-9726-1423 and Kotikov, A. V. (2013). On DIS Wilson coefficients in N=4 super Yang-Mills theory. Physics Letters B, 725(4-5), pp. 394-401. doi: 10.1016/j.physletb.2013.07.013

Abstract

In this Letter we evaluate Wilson coefficients for “deep inelastic scattering” (DIS) in N = 4SYMtheory at NLO in perturbation theory, using as a probe an R -symmetry conserved current. They exhibit uniform transcendentality and coincide with the piece of highest transcendentality in the corresponding QCD Wilson coefficients. We extract from the QCD result a NNLO prediction for the N = 4SYMWilson coefficient, and comment on the features of its Regge limit asymptotics.
