Hadron Structure in Lattice QCD

Abstract

Recent progress in hadron structure calculations within lattice QCD is reviewed. Results on key observables such as the axial charge, the quark momentum fraction and the spin content of the nucleon are discussed with focus on open issues. Lattice QCD studies of the ${\gamma }^{\ast }N\to \Delta$ transition as well as the $\Delta$ form factors are also presented.
