First moments of nucleon generalized parton distributions in chiral perturbation theory at full one-loop order
arXiv:1402.4979 · doi:10.1103/PhysRevD.89.116002
Abstract
In this paper we present chiral extrapolation formulas for the generalized form factors connected to the first moments of chiral-even generalized parton distributions. For the description of QCD at low energies we employ the framework of two-flavor covariant baryon chiral perturbation theory at full one-loop accuracy. Our results are well suited for the extrapolation of lattice QCD data to physical quark masses.
We have updated the text to match the version published in PRD
