Abstract %${\bar{K}}%$-nuclear bound systems, kaonic nuclei, have been widely discussed as products of the strongly attractive %${\bar{K}} N%$ 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 %${\bar{K}} N%$ (%$\Lambda (1405)%$) to %${\bar{K}} NNNN%$. In the new experiment approved as J-PARC E80, we will measure the %${\bar{K}} NNN%$ (%$A=3%$) system as a first step toward a comprehensive study. Ausführliche Beschreibung
