Simple parametrization of nucleon form factors

This Brief Report provides simple parametrizations of the nucleon electromagnetic form factors using functions of $Q^2$ that are consistent with dimensional scaling at high $Q^2$. Good fits require only four parameters each for $G_{Ep}$, $G_{Mp}$, and $G_{Mn}$ and only two for $G_{En}$.

Fits to nucleon electromagnetic form factors. For $G_{En}$, data using recoil or target polarization [16, 17, 18, 19, 20, 21, 22] are shown as filled circles while data obtained from the deuteron quadrupole form factor [23] are shown as open circles.
