Combined Chiral Dynamics and MIT Bag Model Study of Strong Σ^{(*)}_Q \to Λ_QπDecays

Abstract

The strong decays of the heavy baryons Σ^{(*)}_Q \to Λ_Q πare studied by combining the chiral dynamics and the MIT bag model. In charm sector, we calculate the decay widths Γ(Σ^{(*)}_c\to Λ_cπ) and compare with the experimental data and other theoretical estimations. In addition, we also predict the strong decay widths Γ(Σ^{(*)}_b\to Λ_bπ).
