论文摘要

描述了一种用于构建梅森结合状态问题的贝特盐核内核的新方法。它产生一个封闭形式的内核,与任何可接受的gluon-quark顶点定义的差距方程是对称的(离散和连续)。即使该顶点的示意图含量尚不清楚,该方案也可以促进连续体和晶格方法之间的新协同作用。通过证明在Gluon-Quark顶点中存在着穿着的夸克异常磁矩的存在来说明该框架,这是强烈相互作用的紧急特征,可以补救许多广泛使用的梅森结合状态内核的缺陷,包括伪记录和Vector Meson radial radial兴奋的水平顺序。

A novel method for constructing a Bethe-Salpeter kernel for the meson bound-state problem is described. It produces a closed-form kernel that is symmetry-consistent (discrete and continuous) with the gap equation defined by any admissible gluon-quark vertex. Applicable even when the diagrammatic content of that vertex is unknown, the scheme can foster new synergies between continuum and lattice approaches to strong interactions. The framework is illustrated by demonstrating that the presence of a dressed-quark anomalous magnetic moment in the gluon-quark vertex, an emergent feature of strong interactions, can remedy many defects of widely used meson bound-state kernels, including the level ordering of pseudoscalar and vector meson radial excitations.
