Carla Terschlüsen, Stefan Leupold

摘要:

确定了含有动力学矢量介子的单圈图对赝标介子质量和衰变常数的贡献。因此,一个相对论拉格朗日的赝标量介子八重态和矢量介子九重态。矢量介子在反对称张量表象中给出。作为轻夸克质量的函数,研究了静态和动态矢量介子之间的差异以及有无矢量介子计算之间的差异。

英文摘要:

The contributions of one-loop diagrams with dynamical vector mesons to masses and decay constants of pseudoscalar mesons are determined. Hereby, a relativistic Lagrangian for both the pseudoscalar-meson octet and the vector-meson nonet is used. The vector mesons are given in the antisymmetric tensor representation. Both the differences between static and dynamical vector mesons and the differences between calculations with and without vector mesons are studied as functions of the light quark mass.
