Hadron physics experiments using Hyperon Spectrometer at J-PARC

This paper compiles the ongoing hadron physics experiments utilizing the Hyperon Spectrometer at the J-PARC facility. The J-PARC Hadron Experimental Facility, capable of producing world-class intense kaon, pion, and antiproton beams with momenta up to 2 GeV/c, has opened unprecedented opportunities for a wide range of hadron experiments. Complementing these capabilities, the new Hyperon Spectrometer detector system, composed primarily of a high-rate capable time projection chamber and a 1-T superconducting magnet, has made diverse hadron experiments feasible. The first experiment using the Hyperon Spectrometer was successfully conducted in 2021, and additional experiments are currently in preparation. Furthermore, the expansion plans for the J-PARC Hadron Experimental Facility and upgrades to the Hyperon Spectrometer are underway. This paper aims to serve as a guide and inspiration for proposing new hadron experiment ideas at J-PARC using the Hyperon Spectrometer.
