摘要：

Recent Lattice QCD calculations predict a weekly bound H-dibaryon or a resonant state near the I > I > threshold although definite results should be waited for with physical quark masses. We propose to search for the H-dibaryon in I > I > production from (K (-), K (+)) reactions off nuclei and also for the weakly bound H-dibaryon by its weak decays to answer the long-standing question about the existence of the H-dibaryon. For this experiment, we plan to construct a large-acceptance hyperon spectrometer with a time projection chamber to detect I > particles with a good momentum resolution. This spectrometer will also enhance the capability of hadron physics at J-PARC.
