An experiment to search for the K− pp bound state was performed via the in-flight 3He(K−, n) reaction using 5.3 × 109 kaons at 1GeV/c at the J-PARC hadron experimental facility. In the semi-inclusive neutron missing-mass spectrum at θlab n = 0◦, no significant peak was observed in the region corresponding to K− pp binding energy larger than 80MeV, where a bump stru…
