Charmed baryon strong coupling constants in a light-front quark model

Light-front quark model spin-wave functions are employed to calculate the three independent couplings g_ΣcΛcπ, f_Λc1Σcπ, and f_Λc1*Σcπ of S wave to S wave and P wave to S wave one-pion transitions. It is found that g_ΣcΛcπ=6.81 GeV^-1, f_Λc1Σcπ=1.16, and f_Λc1*Σcπ=0.96×10^-4 MeV^-2. We also predict decay rates for specific strong transitions of charmed baryons.
