Description
In these 20 years, hypernuclear physics has been developed at KEK-PS, BNL-AGS and JLab-CEBAF. Now a new falicity, J-PARC, has started operation. Here I will review the progress of hyupernuclear physics in this period. The most important achievements are (1) the establishment of the (pi,K+) reaction spectroscopy at KEK using a large spectrometer called SKS, which includes neutron-rich Lambda hypernuclei, Sigma-nuclear systems, and weak decays of Lambda hypernuclei, and (2) the development of high precision gamma-ray spectroscopy of Lambda hypernuclei using a dedicated Ge detector array, Hyperball, which revealed precise level schemes of most of p-shell Lambda hypernuclei, and (3) the invention of high-resolution (e,e'K+) spectroscopy of hypernuclei at Jefferson Laboratory.
I will review each of them, in particular, the gamma-ray spectorscopy, and then describe future prospects at J-PARC.
