Recent Lattice QCD predictions for the mass of H-dibaryon pointing to the mass region near ΛΛ and Ξ−p thresholds encourage experimental searches. A dedicated experiment (J-PARC E42) is designed to measure Λpπ−, ΛΛ and Ξ−p decays from the H-dibaryon in the 12C(K-,K+) reaction at the K1.8 beam line of J-PARC. A new superconducting Hyperon Spectrometer is now under commissioning, consisting of a conduction-cooled superconducting dipole magnet and a time projection chamber (HypTPC). This talk will review our new attempt to find evidence supporting the existence of the H-dibaryon in the wide mass range as well as the current status of the Hyperon Spectrometer.
