Abstract：
Considering the flavor SU(3) symmetry-breaking in Λ hyperon and using the relativistic two-quark-cluster theory,the ΛN interaction and phase shifts of elastic ΛN scattering have been studied in the quark potential model with the coupling between the quark and mesons (σ+π) taken into account.
