Hadron phenomenology with Dyson-Schwinger and Bethe-Salpeter equations — •Gernot Eichmann — JLU Giessen, Germany

I will give an overview of recent progress on hadron phenomenology within the Dyson-Schwinger/Bethe-Salpeter equation approach. This includes studies of nucleon resonances and transition form factors from the three-quark Faddeev equation as well as its quark-diquark approximation; a calculation of nucleon Compton scattering and nucleon polarizabilities from the quark level; and an investigation of tetraquarks using the four-quark Bethe-Salpeter equation.
