Abstract
The strong decays of the heavy baryons Σ(*) Q→ΛQπ are studied by combining the chiral dynamics and the MIT bag model. In the charm sector, we calculate the decay widths Γ(Σ(*) c→Λcπ) and compare these with the experimental data and other theoretical estimations. In addition, we also predict the strong decay widths Γ(Σ(*) b→Λbπ).
