Assist. Prof. Dr. Toshiyuki Gogami (Kyoto U): Hypernuclei as a tool to study interactions between baryons

Hypernuclei, which contain a strange quark, are key probes to investigate the strong interaction between baryons with strangeness degrees of freedom. Hypernuclear physics started when the first hypernuclear event was observed in nuclear emulsions that were exposed to cosmic rays. Nowadays, hypernuclear spectroscopy is carried out in state-of-the-art accelerator facilities around the world. Where does the strange quark exist in the nature? Baryons which contain the strange quark are expected to exist in neutron stars where the density could be more than a few times higher than the normal nuclear density. In the seminar, I will introduce hypernuclear spectroscopic research in the past and now. In particular, new experimental attempts at J-PARC (Japan) [1] and JLab (US) [2] will be discussed.
