Description
Elastic lepton-nucleon scattering is arguably the simplest measurable process sensitive to the nucleon's internal structure and dynamics. The spacelike and timelike electromagnetic form factors of the nucleon have been measured with ever increasing precision over a wide range of energies since the 1950's, and these measurements have led to many surprises and discoveries that changed our basic notions of nucleon size, shape, and structure. In this talk I will present an overview of nucleon electromagnetic form factors, including their theoretical definition, their relation to experimental observables, the history and current status of the experimental data over the entire range of momentum transfer Q^2, and the major outstanding questions to be addressed by improved theoretical calculations and future experiments at low and high energies.
