基于非线性实现规范群的有质量Yang-Mills理论中的单圈自能和反项

One-loop Self-energy and Counterterms in a Massive Yang-Mills Theory based on the Nonlinearly Realized Gauge Group

Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri

摘要:

本文计算了我们最近提出的SU(2)Yang-Mills理论的减法方案中矢量介子在一圈处的自能。我们检查物理统一性的实现。由此产生的自质量可以与基于希格斯机制的大质量杨-米尔斯理论中获得的值进行比较,由于希格斯玻色子(包括蝌蚪)的存在而存在额外的项。此外,我们评估了所有的一个循环的计数器必要的下一个订单的计算。通过构造,它们满足模型的所有方程(Slavnov-Taylor,局部函数方程和Landau规范方程)。它们足以使所有的单圈振幅通过编码在局部函数方程中的层次有限。

英文摘要:

In this paper we evaluate the self-energy of the vector mesons at one loop in our recently proposed subtraction scheme for massive nonlinearly realized SU(2) Yang-Mills theory. We check the fulfillment of physical unitarity. The resulting self-mass can be compared with the value obtained in the massive Yang-Mills theory based on the Higgs mechanism, consisting in extra terms due to the presence of the Higgs boson (tadpoles included). Moreover we evaluate all the one-loop counterterms necessary for the next order calculations. By construction they satisfy all the equations of the model (Slavnov-Taylor, local functional equation and Landau gauge equation). They are sufficient to make all the one-loop amplitudes finite through the hierarchy encoded in the local functional equation.
