论文摘要
即使是在轻正面夸克模型（LFQM）中，即使在计算诸如介子衰减常数之类的两点函数的情况下，也在轻时夸克模型（LFQM）中挑战了具有不同电流组件的相同物理可观察物的问题，尤其是从减去电流的问题。在一身电流矩阵元素计算的级别上，我们使用所有可用的组件（包括LFQM中电流的减去组分，符合bakamjian-thomas构造一致），显示了伪尺度和矢量介子衰减常数的独特性。无论当前组件，极化向量和参考帧如何，介子衰减常数在非相互作用的组成夸克和反quark基础上都唯一确定，而成分的相互作用则添加到LFQM中的介子质量运营商中。
The issue of resulting in the same physical observables with different current components, in particular from the minus current, has been challenging in the light-front quark model (LFQM) even for the computation of the two-point functions such as meson decay constants. At the level of one-body current matrix element computation, we show the uniqueness of pseudoscalar and vector meson decay constants using all available components including the minus component of the current in the LFQM consistent with the Bakamjian-Thomas construction. Regardless of the current components, the polarization vectors, and the reference frames, the meson decay constants are uniquely determined in the non-interacting constituent quark and antiquark basis while the interactions of the constituents are added to the meson mass operator in the LFQM.
