论文摘要
手性拉格朗日中间场可以通过包含量表因子的矩阵操作员连接到QCD夸克操作员。这些量表因子矩阵被证明受到手性对称性的约束，导致每种手性拉格朗日nonet的通用量表因子。 QCD Sum-RULES与手性Lagrangian分析的混合角相结合，用于确定$ a_0 $ isotriplet和$ k_0^*$ isodoublet标量介子的比例因子。最终的量表因素验证了通用性属性，从而验证了连接手性拉格朗日中间字段和夸克操作员的比例因子矩阵。
Chiral Lagrangian mesonic fields can be connected to QCD quark operators via matrix operators containing scale factors. These scale factor matrices are shown to be constrained by chiral symmetry, resulting in a universal scale factor for each Chiral Lagrangian nonet. QCD sum-rules, combined with mixing angles from Chiral Lagrangian analyses, are used to determine the scale factors for the $a_0$ isotriplet and $K_0^*$ isodoublet scalar mesons. The resulting scale factors verify the universality property, providing a validation of the scale factor matrices connecting Chiral Lagrangian mesonic fields and quark operators.
