Richards, David

Lattice QCD has an increasing role in understanding the structure of hadrons. In this talk, I will review recent lattice calculations beginning with the electromagnetic form factors, describing the distribution of charge and currents within a nucleon, and the parton distribution functions. I will then describe investigations of some new measures of hadron structure, including the Generalized Parton Distributions and Transverse-Momentum-Dependent distributions, and show how lattice calculations, together with experimental measurements, will enable the construction of a three-dimensional picture of the nucleon. I will conclude with prospects for future advances, including the calculation of isoscalar contributions to hadron structure and calculations at the physical light-quark masses.
