Determining properties of baryon resonances in nuclei

By M.B. Johnson, C.M. Chen, D.J. Ernst and M.F. Jiang

Abstract

Meson-nucleus and photon-nucleus interactions are important sources of information about the medium modifications of baryon resonances in nuclei. Indications of how large the medium effects are for resonances above the {Delta}{sub 33}(1232) are provided by it combined analysis of photonuclear and pion cross sections in the GeV range of energies. Tile existing data indicate a possible 10-20% renormalization of the pion coupling to higher-lying resonances in nuclei
