论文摘要
我们通过将标准模型嵌入$ e_6 $型号中，为最近的$ W $质量测量提供了解决方案。新的$ u（1）$组的存在将$ W $玻色子质量转移到树级，并引入了一个新的量规玻色子$ z^{\ prime} $，该$ z^{\ prime} $，该$已在Collider实验中进行了搜索。在本文中，我们识别了解释新的$ W $质量测量的参数空间，并且与当前的实验$ z^{\ prime} $搜索一致。由于$ u（1）$扩展可以在超对称型号中容纳，因此我们还考虑了$ e_6 $型号的超对称方案，并表明在此类设置中很容易实现125 GEV Higgs。
We propose a solution to the recent $W$ mass measurement by embedding the Standard Model within $E_6$ models. The presence of a new $U(1)$ group shifts the $W$ boson mass at the tree level and introduces a new gauge boson $Z^{\prime}$ which has been searched for at collider experiments. In this article, we identity the parameter space that explains the new $W$ mass measurement and is consistent with current experimental $Z^{\prime}$ searches. As $U(1)$ extensions can be accommodated in supersymmetric models, we also consider the supersymmetric scenario of $E_6$ models, and show that a 125 GeV Higgs may be easily achieved in such settings.
