Description
Decay process of ground state $\Lambda_c\rightarrow ND, ND^*, \Sigma_c\rightarrow \Delta D, \Delta D^*$ are studied in the $^3P_0$ nonrelativistic quark model with all parameters fixed in the sector of light quark. In accordance with the assumption that all baryons in question are made of three quarks, the effective coupling strength of the $^3P_0$ vertex is determined by the decay processes of the $\Sigma(1385)$ baryon. The quark model results are applied to determine the coupling constants in effective field theory.
