NLO light-cone sum rules for the nucleon electromagnetic form factors

High Energy Physics - Phenomenology 2014-01-20 v2

Abstract

We study the electromagnetic nucleon form factors within the approach based on light-cone sum rules. We include the next-to-leading-order corrections for the contributions of twist-three and twist-four operators and a consistent treatment of the nucleon mass corrections in our calculation. It turns out that a self-consistent picture arises when the three valence quarks carry 40%:30%:30%40\%:30\%:30\% of the proton momentum.
