abstract
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(gamma(()*()), pi pi)N, p(gamma(()*()), K)Y, P(gamma(()*()), omega)p and p(gamma(()*()), eta)p. We present results for the Q(2) dependence of the helicity amplitudes of these nonstrange baryons resonances, computed in the framework of the Bethe-Salpeter model developed by the Bonn group. The model describes bound states of three relativistic constituent quarks, interacting through an instantaneous linear confining potential and a residual instanton-induced interaction potential. The seven model parameters were fitted to the best known baryon masses, but no extra parameters are introduced in computing the helicity amplitudes.
