Description

The existence of an exotic nuclear bound state containing an anti-kaon and nucleons (kaonic nucleus) has been believed for a long time since the strong attractive KbarN interaction was confirmed. The simplest kaonic nucleus , K^-pp bound state, is particularly important to establish the existence of the kaonic nucleus, and has been searched for by many experiments. We performed an experiment to measure the K^-pp using in-flight K^- reaction at J-PARC hadron experimental facility, and finally observed a clear signal of K^-pp. The details of the experiment and analysis will be shown in this talk.
