    Modeling Final-State Interactions with a Relativistic Multiple-Scattering Approximation

    We address the issue of nuclear attenuation in nucleon and pion knockout reactions. A selection of results from a model based on a relativistic multiple-scattering approximation is presented. We show transpare...

    A Regge-plus-resonance approach to kaon production on the nucleon

    We present a Regge-inspired effective-Lagrangian framework for electromagnetic KY production from the proton. The framework adopts Regge phenomenology to constrain the background contributions to the reaction amp...

    Helicity amplitudes of nonstrange baryons in the third and fourth resonance region

    Baryon resonances with masses around 1600 MeV and higher come into play already at threshold in meson photo- and electroproduction reactions from the proton such as p(γ (*), ππ)N, p(γ ...

    Electromagnetic properties of strange baryons in a relativistic quark model

    We present some of our results for the electromagnetic properties of excited Σ hyperons, computed within the framework of the Bonn constituent-quark model, which is based on the Bethe-Salpeter approach. The seven...

    The transparency of nuclei to nucleons and pions in a relativistic Glauber approximation

    We present a selection of results obtained within the context of a relativistic eikonal model. First, results of relativistic Glauber calculations for the nuclear transparency extracted from photon-induced pio...

    Electromagnetic KY production from the proton in a Regge-plus-resonance approach

    A Regge-plus-resonance (RPR) description of the p(γ,K)Y and p(e, e′K)Y processes (Y = Λ,Σ 0,+) is presented. The proposed reaction amplitude consists of Regge-trajectory exchanges in the t ch...

    Helicity amplitudes and electromagnetic decays of hyperon resonances
