Dynamical study of light scalar mesons below 1 GeV in a flux-tube model

  • The light scalar mesons below 1 GeV configured as tetraquark systems are studied in the framework of the flux-tube model. Comparative studies indicate that a multi-body confinement, instead of the additive two-body confinement, should be used in a multiquark system. The σ and κ mesons could be well accommodated in the diquark-antidiquark tetraquark picture, and could be colour-confinement resonances. The m a0(980) and m f0(980) mesons are not described as m KK molecular states and nsns diquark-antidiquark states. However, the mass of the first radial excited state of the diquark-antidiquark state, nnnn is 1019 MeV, is close to the experimental data of the m f0(980).

Abstract: The light scalar mesons below 1 GeV configured as tetraquark systems are studied in the framework of the flux-tube model. Comparative studies indicate that a multi-body confinement, instead of the additive two-body confinement, should be used in a multiquark system. The σ and κ mesons could be well accommodated in the diquark-antidiquark tetraquark picture, and could be colour-confinement resonances. The m a0(980) and m f0(980) mesons are not described as m KK molecular states and nsns diquark-antidiquark states. However, the mass of the first radial excited state of the diquark-antidiquark state, nnnn is 1019 MeV, is close to the experimental data of the m f0(980).
