    "abstract": "It should be a typical subject in this workshop to explore possible change of\nhadron properties in association with that of QCD vacuum due to an\nenvironmental change. In this report, we first summarize what hadrons are\nexpected to show such a change and how they do. Then we propose several\nexperiments including the ones utilizing electron and photon beams for\nexamining possible restoration of chiral symmetry in nuclei and the possible\nexistence of the sigma meson. The experiments are based on the observation that\nthe sigma meson may decrease the mass and the width along with the partial\nrestoration of chiral symmetry in the medium.",
