Abstract

We provide an updated global extraction of the neutron magnetic form factor, including new extractions from ³H-³He comparisons at Jefferson Lab. Our new global fit addresses discrepancies between previous data sets at modest momentum transfer by separating the uncertainties from world data into normalization and uncorrelated uncertainties. We use this updated global fit, along with previous fits for the other form factors, to extract the neutron and proton transverse charge and magnetization densities and their uncertainties.
