摘要:

在本研究中,我们研究了\cite{Dudal:2023jsu}中提出的规范不变复合算子的重整化,以从规范不变的视角描述$SU(2)\times U(1)$ Higgs模型。为了建立抵消项之间的关系,我们使用了代数重整化方法\cite{Piguet:1995er}。因此,在引入这些复合算子后,我们也推导了该模型的Ward恒等式集合。利用这些Ward恒等式,我们证明了基本场与复合场的关联函数之间的重要精确关系。

英文摘要:

In this work, we investigate the renormalization of the gauge-invariant composite operators proposed in \cite{Dudal:2023jsu} to describe the $SU(2)\times U(1)$ Higgs model from a gauge-invariant perspective. To establish the relationship between the counterterms, we use the Algebraic Renormalization approach \cite{Piguet:1995er}. Therefore, we also derive the set of Ward identities of the model after introducing these composite operators. Using these Ward identities, we demonstrate important exact relations between the correlation functions of elementary fields and composite fields.
