Low-lying 1/2- hidden strange pentaquark states in the constituent quark model

  • We investigate the spectrum of the low-lying 1/2- hidden strange pentaquark states, employing the constituent quark model, and looking at two ways within that model of mediating the hyperfine interaction between quarks-Goldstone boson exchange and one gluon exchange. Numerical results show that the lowest 1/2- hidden strange pentaquark state in the Goldstone boson exchange model lies at~1570 MeV, so this pentaquark configuration may form a notable component in S11(1535) if the Goldstone boson exchange model is applied. This is consistent with the prediction that S11(1535) couples very strongly to strangeness channels.

Abstract: We investigate the spectrum of the low-lying 1/2- hidden strange pentaquark states, employing the constituent quark model, and looking at two ways within that model of mediating the hyperfine interaction between quarks-Goldstone boson exchange and one gluon exchange. Numerical results show that the lowest 1/2- hidden strange pentaquark state in the Goldstone boson exchange model lies at~1570 MeV, so this pentaquark configuration may form a notable component in S11(1535) if the Goldstone boson exchange model is applied. This is consistent with the prediction that S11(1535) couples very strongly to strangeness channels.
