Nucleon electroweak form factors in a meson-cloud model

By Pavia and INFN B. PasquiniPavia U. and Pavia) and INFN S. Boffi(Pavia U.

Abstract

The meson-cloud model of the nucleon consisting of a system of three valence quarks surrounded by a meson cloud is applied to study the electroweak structure of the proton and neutron. The electroweak nucleon form factors are calculated within a light-front approach, by obtaining an overall good description of the experimental data. Charge densities as a function of the transverse distance with respect to the direction of the three-momentum transfer are also discussed
