reactions to search for the 
bound state via the 
He reaction at J-PARCYamaga, Takumi*; Tanida, Kiyoshi

We have searched for the simplest kaonic nuclear state, , using the in-flight He reaction at the J-PARC hadron experimental facility. In the semi-inclusive neutron missing-mass spectrum at 
, an excess of yield was observed just below the 
mass-threshold, which cannot be explained by any elementary reactions [PTEP 2015, 061D01]. To understand the missing-mass spectrum of He
, we investigated the elementary reactions using hydrogen and deuterium targets. The 
missing-mass spectrum was well described by the charge-exchange reaction. However, in the 
spectrum, we observed an excess of yield just below the 
mass-threshold, which was similar to that in the He spectrum.
