Future prospects of spectroscopic study of Lambda hypernuclei at JLab and J-PARC HIHR

The ( e , e′K + ) reaction spectroscopy opened a door to high resolution of Λ hypernuclei at JLab and it is currently the only technique give sub-MeV energy for wide-mass range hypernuclei. New experiments from light heavy are under preparation solve hypertriton puzzle, clarify charge symmetry breaking clue hyperon puzzle or neutron stars. As hypernuclear precision experiment with other than electron beams, there newly proposed using π K new HIHR beamline, which key facility in J-PARC hadron experimental extension project. beamline adopts momentum dispersion match will enable us perform isospin partners studied beams JLab.
