Abstract

Motivated by the LHCb observations of P_c and P_cs states, we systematically investigate the hidden-charm double-strange pentaquark system (nsscc) using the resonating group method within the quark delocalization color screening model (QDCSM). By dynamically incorporating channel coupling effects, five resonance states are identified with J^P = 1/2^- and 3/2^-. Their masses, widths, and dominant decay channels are predicted, providing critical guidance for future experimental searches.
