Abstract

The possible existence of deeply-bound $\bar K$K¯ -nuclear bound states, kaonic nuclei, has been widely discussed as products of the strongly attractive $\bar K$K¯ N interaction in I = 0 channels. Investigations of those exotic states will provide us unique information of the $\bar K$K¯ N interaction below the threshold, which is still not fully understood so far. Recently, we observed the simplest kaonic nuclei, $\bar K$K¯ NN, having a much deeper binding energy than normal nuclei via inflight (K, N) reactions at the J-PARC E15 experiment. For further studies, we have proposed a series of experimental programs for the systematic investigation of light kaonic nuclei, from $\bar K$K¯ N (Λ(1405)) to $\bar K$K¯ NNNN. We will measure the $\bar K$K¯ NNN (A = 3) system at the new experiment approved as J-PARC E80, as a first step toward a comprehensive study.
