Research Abstract

Spectrum and form factors of the baryon resonances provide basic information on the dynamics of the non-perturbative strong interaction at low energy. In this study, we have investigated(1) spectrum and form factors of baryon excited states from the analysis of the photon and electron induced meson production reaction,(2) signal of the strange dibaryon in the meson production reaction. From those studies we have revealed the hadronic structure of the excited hadron states.
