$0^{-+}$胶球的量子手征场论

Quantum chiral field theory of $0^{-+}$ glueball

Bing An Li

摘要:

本文提出了$0^{-+}$胶球的手征场论。夸克算符与$0^{-+}$胶球场之间的耦合由U(1)反常揭示出来。这个理论的拉格朗日量是通过在赝标、矢量和轴矢量介子的手征场论的拉格朗日量上加上$0^{-+}$胶球场而构造的。定量研究了$m=1.405\textrm{GeV}$的$0^{-+}$胶球的物理过程。理论预测可用于识别$0^{-+}$胶球。

英文摘要:

A chiral field theory of $0^{-+}$ glueball is presented. The coupling between the quark operator and the $0^{-+}$ glueball field is revealed from the U(1) anomaly. The Lagrangian of this theory is constructed by adding a $0^{-+}$ glueball field to a successful Lagrangian of chiral field theory of pseudoscalar, vector, and axial-vector mesons. Quantitative study of the physical processes of the $0^{-+}$ glueball of $m=1.405\textrm{GeV}$ is presented. The theoretical predictions can be used to identify the $0^{-+}$ glueball.
