1304.7252 (Lorenzo Bianchi et al.)

On DIS Wilson coefficients in N = 4 super Yang-Mills theory    [PDF]

Lorenzo Bianchi, Valentina Forini, Anatoly V. Kotikov
In this note we evaluate Wilson coefficients for "deep inelastic scattering" (DIS) in N=4 SYM theory 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=4 SYM Wilson coefficient, and comment on the features of its Regge limit asymptotics.
