A light-front description of electromagnetic form factors for $J\le 3/2$ hadrons

Abstract

A review of the hadron electromagnetic form factors obtained in a light-front constituent quark model, based on the eigenfunctions of a mass operator, is presented. The relevance of different components in the q-q interaction for the description of hadron experimental form factors is analysed.
