Neutron charge radius from intrinsic quark flavour generation

Abstract

The finite, non-zero mean square neutron charge radius is understood in the present work to have a topological origin from an intrinsic neutron configuration in the Lie group U(3). We introduce up and down quark orbits in the configuration for the neutron mass eigenstate. From reciprocal Gaussian curvatures we infer a mean square charge radius of −0.1075 square fermis a few standard deviations away from the world average of −0.1161 square fermis.
