Further Theoretical Analysis on the Reaction for the Bound-State Search in the J-PARC E15 Experiment
Based on the scenario that a bound state is generated and it
eventually decays into , we calculate the cross section of the
reaction, which was recently measured
in the J-PARC E15 experiment. We find that the behavior of the calculated
differential cross section ,
where and are the invariant mass
and momentum transfer in the reaction in the laboratory frame,
respectively, is consistent with the experiment. Furthermore, we can reproduce
almost quantitatively the experimental data of the invariant mass
spectrum in the momentum transfer window . These facts strongly suggest that the bound
state was indeed generated in the J-PARC E15 experiment.Comment: 4 pages, 4 EPS figures, talk given at the 8th International
