具有非线性实现规范群的电弱模型的单圈自能

One-loop Self-energies in the Electroweak Model with Nonlinearly Realized Gauge Group

Daniele Bettinelli, Ruggero Ferrari, Andrea Quadri

摘要:

本文计算了规范群非线性实现的电弱模型中W,Z介子在一般D维中的自能。在这个模型中,希格斯玻色子参数不存在,而第二个质量参数与辐射修正的尺度一起出现。我们估计这些参数的轻子和规范玻色子数据的简化拟合。我们检查物理幺正性和红外发散的情况下。使用朗道规。

英文摘要:

We evaluate at one loop the self-energies in generic D dimensions for the W,Z mesons in the Electroweak model where the gauge group is nonlinearly realized. In this model the Higgs boson parameters are absent, while a second mass parameter appears together with a scale for the radiative corrections. We estimate these parameters in a simplified fit on leptons and gauge bosons data. We check physical unitarity and the absence of infrared divergences. Landau gauge is used.
