Possible open charm molecular pentaquarks from ${\Lambda }_c{K}^{(\ast )}/{\Sigma }_c{K}^{(\ast )}$ interactions

Rui Chen, Qi Huang

In this work, we adopt the one-boson-exchange model to study the $Y_c{K}^{(\ast )}(Y_c={\Lambda }_c,{\Sigma }_c)$ interactions. After considering both of the $S-D$ wave mixing effects and the coupled c…
