Abstract
We study one-pion transitions between charm baryon states in the framework of a relativistic three-quark model. We calculate the charm baryon-pion coupling factors that govern the S-wave, P-wave and D-wave one-pion transitions from the s-wave and the lowest lying p-wave charm baryon states down to the s-wave charm baryon states. For these we obtain: g_{\\Sigma_c\\Lambda_c\\pi}=8.88 GeV^{-1}, f_{\\Lambda_{c1}\\Sigma_c\\pi}=0.52 and f_{\\Lambda_{c1}^*\\Sigma_c\\pi}=69.6 GeV^{-2}. We compare our rate predictions for the one-pion transitions with experimental results.
