英文摘要	Several compact sss (c) over bar 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, J(P) = 1/2(-)(E= 5180 MeV, Gamma = 20MeV), 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. (C) 2019 The Author(s).
