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 - p p , 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 ¯ N N N N . In the new experiment approved as J-PARC E80, we will measure the K ¯ N N N ( A = 3 ) system as a first step toward a comprehensive study.
