Parameterization and applications of the low-$Q^2$ nucleon vector form factors

Understand

We present the proton and neutron vector form factors in a convenient parametric form that is optimized for momentum transfers $\lesssim$ few GeV$^2$.

• The form factors are determined from a global fit to electron scattering data and precise charge radius measurements.
• A new treatment of radiative corrections is applied.
• This parametric representation of the form factors, uncertainties and correlations provides an efficient means to evaluate many derived observables.
