Outline of Final Research Achievements

The origin of hadron mass is thought to be due to the spontaneous breaking of chiral symmetry, not only the Higgs mechanism, as Nambu advocated. In order to obtain the experimental evidence of the idea, we proposed the systematic measurement of vector meson mass in nuclei with the world best resolution and statistics through the di-electron decay at J-PARC hadron experimental facility. In order to construct a spectrometer for the experiment, we have developed the GEM tracker, Hadron blind detector and read-out electronics, and produced a part of them which consist the spectrometer. Also, by the simulation based on the achieved performance of the developed detectors, we evaluated the sensitivity to the spectral modification of the phi meson using the limited number of the detectors, only eight modules out of 26 modules originally proposed.
