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 pi(+/-) beams at the K1.8 beam line will be used mostly for hypernuclear experiments. The gamma-spectroscopy of Lambda hypernuclei using the (K-, pi(-)) reaction and the spectroscopy of neutron-rich hypernuclei via the (pi(-), K+) reaction are planned to be studied. As for Strangeness = -2 systems, experiments for Xi hypernuclear spectroscopy via the (K-, K+) reaction, double Lambda hypernuclei by the hybrid emulsion method, and Xi(-)-atomic X rays will be carried out.
