Among the light baryons, the $J^\pi = \frac{1}{2}^-$ $\Lambda(1405)$ baryon is an important special case by sitting just below the $\bar{K}N$ threshold and decaying almost exclusively to $\Sigma\pi$. It has long been hypothesized to be either a molecular bound state or a continuum resonance, or that it is a simple quark-model resonance, the $P$-wave companion of the $\Lambda(1520)$. In...
The GlueX experiment located at Jefferson Lab studies the spectrum of hadrons using photoproduction on a $LH_2$ target in a wide variety of final states. With its detector system capable of measuring neutral and charged final state particles over almost the full solid angle, and very good particle identification capabilities, GlueX can measure many different hadrons containing strangeness. A...
A new magnetic spectrometer S-2S is being installed at the K1.8 beam line of J-PARC, Japan. The installation is planned to be completed this year. The first experimental attempt is to measure the binding energy of a $\Xi$ hypernucleus $^{12}_{\Xi}$Be by a missing-mass method through the $(K^{-},K^{+})$ reaction. An expected binding-energy resolution is about $2~$MeV (FWHM) which is the best...
Study of nuclear matter attracts wide interests in the field of hadron physics research. A project to study high-density nuclear matter using heavy ion collisions in a beam energy range of few GeV is being prepared at J-PARC. According to past experiments and model calculations, such heavy ion collisions can produce a high-baryon density matter, which has few times larger density than a normal...
The J-PARC Hadron Experimental Facility was constructed with an aim to explore the origin and evolution of matter in the universe through the experiments with intense particle beams. In the past decade, many results on particle and nuclear physics have been obtained at the present facility. To expand the physics programs to unexplored regions never achieved, the extension project of the Hadron...
The present status and perspectives of hypernuclear physics (strangeness nuclear physics) are summarized based on the presentations reported in the HYP2022 conference. The talk will cover experimental activities at J-PARC, JLab, LHC, DA$\Phi$NE, GSI/FAIR, MAMI etc., and highlights of recent results and near future plans are reviewed. By combining with theoretical progress, a personal view of...
