Spectroscopic study of heavier quark baryons using hadron beam at J-PARC

Understanding hadron formation is one of the fundamental goals of hadron physics. Spectroscopic observations of charmed and multi-strange baryons can provide a unique opportunity to study internal structure of hadrons. Systematic studies of charmed and multi-strange baryons are expected to reveal effective degrees of freedom and their interaction for describing hadron structures. The hadron experimental facility at J-PARC aims at revealing hadron structures using the world's most intense meson beam. The high-intensity and high-momentum beams can provide many opportunities to investigate the structure of hadrons, in which charm and strange quarks play an important role. High-momentum beam line, called the $\pi$20 beam line, is under construction, and the charmed baryon spectroscopy experiment is planned. In the future, the Hadron Experimental Facility are extended to include beam lines with special capabilities. Dedicated high-momentum beam line called the K10 beam line, which can provide separated $K^−$ up to 10 GeV/$c$, is planned to be constructed. We promote systematic studies of charmed and multi-strange baryons using intense hadron beams at J-PARC.
