We introduce physics interests of hypernuclei related to astrophysics. Particularly, some remarkable information from precision spectroscopic studies of hypernuclei has been provided, which should be taken into consideration on arguments on hyperon constituent in a neutron star core. Further precision spectroscopic studies of hypernuclei have to be carried out at J-PARC.
We describe physics interests of hypernuclei. Spectroscopic studies of hypernuclei carried out for more than 20 years at the KEK 12-GeV Proton Synchrotron are overviewed. Precision spectroscopic studies via the (pi,K{sup +}) reactions developed at KEK are reviewed. Among them, some remarkable results are introduced.
J-PARC Hadron Experimental Facility is designed as a multi-purpose experimental facility for particle and nuclear physics experiments using high-intensity secondary particles (Kaons, pions, and so on) produced by 50 GeV-15 muA (750 kW) primary proton beams. Currently, three secondary beam lines (K 1.8 BR, K 1.8, and KL) have been constructed. The first beam extraction from 50 GeV proton synchrotron was on January 27{sup th}, 2009, and the beam commissioning of the primary and secondary beam lines are on going. The present article reports construction status and beam commissioning of Hadron Experimental Facility in detail.
