Description
The electromagnetic transition form factors of the nucleon provide a sensitive probe of the dynamics responsible for hadron structure in quantum chromodynamics. In particular, they offer insight into how one of the manifestations of emergent hadronic mass, namely dynamical chiral symmetry breaking, is reflected in changes to hadron substructure, including the formation of non-pointlike dynamical diquark correlations. In this talk, we present a symmetry-preserving framework, based on continuum Schwinger methods, for calculating the electromagnetic transition form factors of the nucleon to its excited states, with particular emphasis on parity-changing transitions.
