Charmed Baryon Strong Coupling Constants in a Light-Front Quark Model

Abstract

Light-Front quark model spin wave functions are employed to calculate the three independent couplings g_{Σ_c Λ_c π}, f_{Λ_{c1} Σ_c π} and f_{Λ^{*}_{c1} Σ_c π} of S-wave to S-wave and P-wave to S-wave one-pion transitions. It is found that g_{Σ_c Λ_c π}=6.81 MeV^{-1}, f_{Λ_{c1} Σ_c π}=1.16 and f_{Λ^{*}_{c1} Σ_c π}=0.96 . 10^{-4} MeV^{-2}. We also predict decay rates for specific strong transitions of charmed baryons.
