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 loffe sum rules and also to lattice QCD simulations. (C) 2011 Elsevier B.V. All rights reserved.
