The nucleon wave function at the origin

High Energy Physics - Phenomenology 2015-03-17 v2

Abstract

We calculate the next-to-leading order perturbative corrections to the SVZ sum rules for the coupling f_N, the nucleon leading twist wave function at the origin. The results are compared to the established Ioffe sum rules and also to lattice QCD simulations.
