Abstract

K¯ -nuclear bound systems, kaonic nuclei, have been widely discussed as products of the strongly attractive K¯ 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 K¯ N (Λ (1405)) to K¯ NNNN. In the new experiment approved as J-PARC E80, we will measure the K¯ NNN (A= 3) system as a first step toward a comprehensive study.
