N2 - A recent claim from the LHCb collaboration on the observation of two hidden-charm pentaquark states revives hopes for experimental discoveries of other multiquark baryonic states such as the H-dibaryon with a 6-quark (uuddss) configuration. Recent theoretical predictions for the mass of H-dibaryon pointing to the mass region near the ΛΛ threshold also encourage experimental searches. We have proposed a dedicated experiment to search for the H-dibaryon in the bound and unbound mass regions near ΛΛ threshold. We plan to measure production of Λ pπ−, ΛΛ and Ξ− p systems in the12C(K−, K+) reaction at J-PARC. We are now constructing a large-acceptance hyperon spectrometer consisting of a superconducting dipole magnet and a time projection chamber, which allows conclusive experimental searches with a precise 1-MeV mass resolution.
