Transition decay widths by one-pion emissions for excited heavy baryons with a single heavy (charm and bottom) quark are investigated by following the heavy-quark symmetry and its breaking effects at O(1/M) for a heavy-baryon mass M. Based on heavy-baryon effective theory, interaction Lagrangians for the heavy baryons with an axial-vector current induced by a pion are constructed. We show that the transition decay widths in several channels are related up to O(1/M). The results will be useful in the experimental study of excited heavy baryons.
