Strangeness at J-PARC

Strangeness nuclear physics is one of the main fields to be explored at the J-PARC Hadron Hall. The K ^?? and π ^± beams at the K1.8 beam line will be used mostly for hypernuclear experiments. The γ-spectroscopy of Λ hypernuclei using the K ^??,π ^?? reaction and the spectroscopy of neutron-rich hypernuclei via the π ^??,K ^?+? reaction are planned to be studied. As for Strangeness =???2 systems, experiments for Ξ hypernuclear spectroscopy via the K ^??,K ^?+? reaction, double Λ hypernuclei by the hybrid emulsion method, and Ξ^?-atomic X rays will be carried out.
