Abstract

We report on preliminary results of the J-PARC E15 experiment aiming to search for the simplest kaonic-nuclear bound-state, K-pp via in-flight 3He(K-; n) reaction. The first physics data-taking was performed with 5 × 109 incident kaons on the 3He target, and 3 × 105 neutrons were collected by a forward neutron counter placed 15 m away from center of the target at 0 degrees. The semi-inclusive neutron spectrum shows clear peak structure composed of the quasi-elastic K-n → K-n and the charge exchange K-p → K0n reactions as expected.
