The electric form factor of the neutron and its chiral content
Abstract
Considering the nucleon as a system of confined valence quarks surrounded by pions we derive a Galster-like parameterization of the neutron electric form factor GEn. Furthermore, we show that the proposed parameterization can be linked to properties of the pion cloud. By this, the high quality data for the pion form factor can be used in predictions of GEn in the low Q2 region, where the direct double polarization measurements are not available.
