He(
reaction at J-PARCSekihara, Takayasu; Oset, E.*; Ramos, A.*
In this contribution we theoretically investigate what is the origin of the peak structure observed in the E15 experiment of the in-flight He( reaction at J-PARC, which could be a signal of the lightest kaonic nuclei, that is, the 
state. For the investigation, we evaluate the 
invariant mass spectrum assuming two possible scenarios to interpret the experimental peak. One assumes that the 
resonance is generated after the emission of an energetic neutron from the absorption of the initial 
, not forming a bound state with the remaining proton. The other scenario implies that, after the emission of the energetic neutron, a 
bound state is formed. Our results show that the experimental signal observed in the in-flight He( reaction at J-PARC is qualitatively well reproduced by the assumption that a bound state is generated in the reaction, definitely discarding the interpretation in terms of an uncorrelated 
state.
