Study of Neutron-Rich Hypernuclei by the (π−, K+) Reaction at J-PARC

We are planning to perform an experiment at J-PARC and produce new neutron-rich Λ hypernuclei by using the (π −, K +) reaction (J-PARC E10). As the first step, we are planning to produce \({^6_{\Lambda}{\rm H}}\) hypernuclei with a 6Li target. To conduct this experiment, we are developing new detectors, those are scintillating fiber tracker, and silicon strip detector, for high rate operation to aim at increasing beam intensity up to 107/spill. As a result of beam test in Jun 2012, we are going to use high-rate beam at least 107/spill.
