Description
The proton has played a major role in the scientific endeavor. For instance, over a century ago, it exposed the substructure of the atom and, decades later, empirical indications about the existence of quarks. Its scrutiny is thus crucial in understanding the most complicated facets of quantum chromodynamics. In this talk we present a symmetry-preserving scheme, based upon continuum Schwinger methods, to calculate the electromagnetic transitions of the nucleon to its excited states, emphasizing those that produce a change in parity. Among other things, this allows us to inquire on how one of the corollaries of the Emergent Hadronic Mass, namely Dynamical Chiral Symmetry Breaking, manifests itself in changes in the hadron substructure; in particular, leading to the formation of non point-like dynamical diquarks.
