A new parameterization of the nucleon elastic form factors

Abstract

The nucleon elastic form factors are generally interpreted as a mapping of the charge and magnetic current distributions of the proton and neutron. New high Q^2 measurements have opened up fundamental questions about G_ep that remain to be answered. This talk will summarize current developments surrounding the nucleon form factors and explain why they are important to neutrino physicists. New parameterizations of the nucleon form factors, suitable for use by neutrino physicists, will be introduced and discussed.
