标题： $g_{K N Λ}$ and $g_{K N Σ}$ from QCD sum rules

摘要： $g_{K N \Lambda}$和$g_{K N \Sigma}$是通过一种基于 QCD 精炼求和规则的方法计算的，该方法由 Reinders、Rubinstein 和 Yazaki 提出，用于提取强子与金石玻色子的耦合。 通过包含奇夸克质量的贡献并假设奇夸克凝聚和上、下夸克凝聚取不同值来考虑 SU(3) 对称性破缺效应。 我们得到$g_{K N \Lambda}/\sqrt{4 \pi} = - 1.96 $和$g_{K N \Sigma}/\sqrt{4 \pi} = 0.33 $。 显示英文摘要

摘要： $g_{K N \Lambda}$ and $g_{K N \Sigma}$ are calculated using a QCD sum rule motivated method used by Reinders, Rubinstein and Yazaki to extract Hadron couplings to goldstone bosons. The SU(3) symmetry breaking effects are taken into account by including the contributions from the strange quark mass and assuming different values for the strange and the up down quark condensates. We find $g_{K N \Lambda}/\sqrt{4 \pi} = - 1.96 $ and $g_{K N \Sigma}/\sqrt{4 \pi} = 0.33 $
