Precise spectroscopy of Lambda hypernuclei with electron and meson beams
Our knowledge of macroscopic features of neutron stars (NS) have been greatly progressed by recent astronomical observations. However, hyperon appearance in NS contradicts to the existence of NS with two solar masses (hyperon puzzle). For the microscopic understanding of nuclear matter with hyperons, there are growing efforts worldwide in hypernuclear spectroscopy. I will review recent experimental activities about hypernuclear studies with electron beams at JLab and meson beams at J-PARC.
