英文摘要	Here we investigate the decay patterns of the low-lying hidden strangeness nucleon resonances ( N-s (s) over bar) via the strangeness channels by employing the chiral Lagrangian approach, where the N-s (s) over bar states are treated as compact pentaquark states. The S-wave decays of these states to the PB (pseudoscalar meson and baryon) and VB (vector meson and baryon) channels are studied. According to the obtained masses and decay properties, we find four states, namely, N-s (s) over bar (1874) with quantum numbers I (J(P)) = 1/2(1/2(-)), N-s (s) over bar (1885) with I (J(P)) = 1/2(3/2(-)), N-s (s) over bar(2327) with I (J(P)) = 1/2(1/2(-)), and N-s (s) over bar(2252) with I (J(P)) = 1/2(3/2(-)), may be associated with the well-established nucleon resonances N(1895) and N(1875) and with the resonances N(2355) and N (2250) newly predicted by the CLAS Collaboration, respectively. In addition, several other obtained hidden strangeness nucleon resonances may be expected to be dominant components of the predicted missing resonances in the literature.
