Probing the nature of the anticharmed-strange pentaquark states: mass spectra, decays, and magnetic moments

Within the framework of the quark delocalization color screening model, a systematic investigation of the anticharmed-strange pentaquark system is performed using the resonance group method. The currently estimations predict three bound states with estimated masses to be 2886 MeV, 3039 MeV, and 3153 MeV, respectively. Additionally, three resonance states are identified in various scattering phase shifts processes. Among them, two resonance states D and ^D^ with quantum number 12 (12^-) are detected in channels NDₒ^ and ND, and D^ and D, with masses and decay widths of (Mₑ=30533055 MeV, Tₓ₎ₓ₀₋=13. 013. 4 MeV) and (Mₑ=33893390 MeV, Tₓ₎ₓ₀₋=10. 4 MeV), respectively. In the D^ and D^ channels, a resonance state with quantum number 12 (32^-) is discovered, with its mass and decay width being 32503252 MeV and 4. 4 MeV, respectively. These predicted pentaquark states have csnnn quark compositions, allowing them to be recognized as genuine pentaquark states. To validate these predictions, it is expected that upcoming experiments will further explore the predicted resonance and bound states in these possible decay channels.
