We study the hadron structure in continuum QCD within the framework of Dyson-Schwinger equations (DSEs). DSEs provide a controlled scheme for computations in continuum QCD, capable of simultaneously incorporating confinement and expressing dynamical chiral symmetry breaking, and then identifying observable signals of these emergent phenomena. The light front quantities that describe the hadron structrure, such as the parton distribution amplitudes (PDAs) and form factors, are then obtained in several schemes. The further generalization of such QCD-connected computations is a long-term goal of hadron physics practitioners.
