Production of singly charm pentaquark from meson-baryon interaction in B decay

In the paper, we discuss the possible interpretation of the $J^P=1\mathrm{/}{2}^{-}$ singly charm pentaquark as hadronic molecules. With the effective Lagrangian method, we further analyze the production properties of singly charm pentaquark from decays of $B$ meson, including strong coupling constants and production branching ratios of the charm pentaquark. Our numerical results show that the branching ratio of production of pentaquark from B meson can reach to order of ${10}^{-6}$.
