摘要
在Λ超子中考虑味SU(3)对称破缺,在夸克势模型基础上引进夸克与σ^-和π^-介子场的耦合,运用相对论性的两夸克集团理论,研究了ΛN作用势、~3S_1道和~1S_0道的ΛN弹性散射相移.
Considering the flavor SU(3) symmetry-breaking in A- hyperon and using the relativistic two-quark-cluster theory, the AN interaction and phase shifts of elastic AN scattering have been studied in the quark potential model with the coupling between the quark and mesons (σ+Π) taken into account.
