Recent Results and Future Prospects of Kaonic Nuclei at J-PARC
FEW-BODY SYSTEMS(2021)
摘要
K̅ -nuclear bound systems, kaonic nuclei, have been widely discussed as products of the strongly attractive K̅ N interaction in I = 0 channels. Recently, we demonstrated that kaonic nuclei can be produced via in-flight (K^-,N) reactions using the low-momentum DC kaon beam at the J-PARC E15 experiment. We observed the simplest kaonic nuclei, K^-pp , having a much deeper binding energy than normal nuclei. For further studies, we have proposed a series of experimental programs for the systematic investigation of light kaonic nuclei, from K̅ N ( Λ (1405) ) to K̅ NNNN . In the new experiment approved as J-PARC E80, we will measure the K̅ NNN ( A=3 ) system as a first step toward a comprehensive study.
