Findings

Five resonance states identified with J^P = 1/2^- and 3/2^-

Predicted masses and widths for these states

Guidance for experimental searches

Abstract

Motivated by the LHCb observations of $P_c$ and $P_{cs}$ states, we systematically investigate the hidden-charm double-strange pentaquark system ($nssc\bar{c}$) 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.
