Recent results and future prospects of kaonic nuclei at J-PARC

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.
