Overview of nucleon structure

Abstract: The quark-gluon properties of the nucleon are probed by a host of recent and planned experiments. These involve elastic, deep-inelastic, semi-inclusive deep-inelastic (SIDIS), and deeply-virtual Compton scattering. A light-front description is naturally applied to interpret all of these processes. The advantages of this approach will be discussed The talk will then focus on the transverse charge and magnetization densities of the nucleons and the use of SIDIS to reveal the non-spherical shape of the nucleon. We find that the central charge density of the neutron is negative, that the magnetization density of the proton extends further in space than the charge distribution, and that the shape of the nucleon, as measured by the spin-dependent density, is not spherical.
