Electromagnetic Excitation of the Baryons Within the Covariant Spectator Formalism

摘要

We present some results on the electromagnetic structure of the Δ (1232), the N* (1535), and the Ω− baryons, obtained within the Covariant Spectator framework. We discuss their connection to calculations of QCD in the lattice and the role of the meson cloud in the γ N → N* (1535) transition.
