A new N* resonance as a hadronic molecular state

  • We report our recent work on a hadronic molecule state of the KKN system with I=1/2 and JP=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 JP=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.

A new N* resonance as a hadronic molecular state

    Corresponding author: Daisuke Jido,

Abstract: 

We report our recent work on a hadronic molecule state of the KKN system with I=1/2 and JP=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 JP=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.
