Neutron negative central charge density: An inclusive-exclusive connection

Models of generalized parton distributions at zero skewness are used to relate the behavior of deep inelastic scattering quark distributions, evaluated at high $x$, to the transverse charge density evaluated at small distances. We obtain an interpretation of the recently obtained negative central charge density of the neutron. The $d$ quarks dominate the neutron structure function for large values of Bjorken $x$, where the large momentum of the struck quark has a significant impact on determining the center of momentum and thus the “center” of the nucleon in the transverse position plane.
