抄録

Several compact ssscc¯ pentaquark resonances are predicted in a potential quark model. The Hamiltonian is the best available one, which reproduces the masses of the low-lying charmed and strange hadrons well. Full five-body calculations are carried out by the use of the Gaussian expansion method, and the relevant baryon-meson thresholds are taken into account explicitly. Employing the real scaling method, we predict four sharp resonances, JP=1/2 (E=5180 MeV, Γ=20 MeV), 5/2 (5645 MeV, 30 MeV), 5/2 (5670 MeV, 50 MeV), and 1/2+ (5360 MeV, 80 MeV). These are the candidates of compact pentaquark resonance states from the current best quark model, which should be confirmed either by experiments or lattice QCD calculations.
