Generalized parton distributions for the pion in chiral perturbation theory

High Energy Physics - Phenomenology 2010-04-05 v2 High Energy Physics - Lattice

Abstract

Generalized parton distributions provide a unified parameterization of hadron structure and allow one to combine information from many different observables. Lattice QCD calculations already provide important input to determine these distributions and hold the promise to become even more important in the future. To this end, a reliable extrapolation of lattice calculations to the physical quark and pion masses is needed. We present an analysis for the moments of generalized parton distributions of the pion in one-loop order of chiral perturbation theory.
