Abstract：
We report our recent work on a hadronic molecule state of the KKN system with I=1/2 and J^P=1/2⁺. We assume that the Λ(1405) resonance and the scalar mesons, f₀(980), a₀(980), are reproduced as quasi-bound states of KN and KK, respectively. Performing non-relativistic three-body calculations with a variational method for this system, we find a quasibound state of the KKN system around 1910 MeV below the three-body breakup threshold. This state corresponds to a new baryon resonance of N^* with J^P=1/2⁺. We find also that this resonance has the cluster structure of the two-body bound states keeping their properties as in the isolated two-particle systems. We also briefly discuss another hadronic molecular state composed by two K and one N, which corresponds to a Ξ^* resonance.

Abstract:

We report our recent work on a hadronic molecule state of the KKN system with I=1/2 and J^P=1/2⁺. We assume that the Λ(1405) resonance and the scalar mesons, f₀(980), a₀(980), are reproduced as quasi-bound states of KN and KK, respectively. Performing non-relativistic three-body calculations with a variational method for this system, we find a quasibound state of the KKN system around 1910 MeV below the three-body breakup threshold. This state corresponds to a new baryon resonance of N^* with J^P=1/2⁺. We find also that this resonance has the cluster structure of the two-body bound states keeping their properties as in the isolated two-particle systems. We also briefly discuss another hadronic molecular state composed by two K and one N, which corresponds to a Ξ^* resonance.
