Abstract

Light-front quark model spin-wave functions are employed to calculate the three independent couplings

g_{Σ_{c} Λ_{c} π},

f_{Λ_{c 1} Σ_{c} π},

and

f_{Λ_{c 1}^{*} 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 {GeV}^{- 1},

f_{Λ_{c 1} Σ_{c} π} = 1.16,

and

f_{Λ_{c 1}^{*} Σ_{c} π} = 0.96 \times 10^{- 4} {MeV}^{- 2} .

We also predict decay rates for specific strong transitions of charmed baryons.
