Pentaquark interpretation of

Motivated by the recent observation of the $$\Lambda _c(2910)^+$$ state in the $$\Sigma _{c}(2455)^{0,++}\pi ^{\pm }$$ spectrum by the Belle Collaboration, we investigate the explanation of $$\Lambda _{c}$$ states within the pentaquark framework using the quark delocalization color screening model (QDCSM). To check for bound states and resonance states, we utilize the real-scaling method. Additionally, we calculate the root mean square of cluster spacing to study the structure of the states and further estimate whether a state is a resonance state or not. Our numerical results show that $$\Lambda _{c}(2910)$$ cannot be interpreted as a molecular state, and $$\Sigma _{c}(2800)$$ cannot be explained as the ND molecular state with $$J^P=1/2^-$$. However, we find that $$\Lambda _{c}(2595)$$ can be interpreted as a molecular state with $$J^P=\frac{1}{2}^-$$, where the main component is $$\Sigma _{c}\pi $$. Similarly, we interpret $$\Lambda _{c}(2625)$$ as a molecular state with $$J^P=\frac{3}{2}^-$$, where the main component is $$\Sigma _{c}^{*}\pi $$. We also suggest that $$\Lambda _{c}(2940)$$ is likely to be interpreted as a molecular state with $$J^P=3/2^-$$, where the main component is $$ND^{*}$$. In addition, we predict two new states: a $$J^P=3/2^-$$$$\Sigma _{c}\rho $$ resonance state with a mass of 3140–3142 MeV, and a $$J^P=\frac{5}{2}^-$$$$\Sigma _{c}^*\rho $$ state with a mass about 3187–3188 MeV
