摘要:

将3-3-1模型和左右对称模型看作是$SU(3)_C\otimes SU(3)_L\otimes SU(3)_R$ ~(简称$[SU(3)]^3$)规范群的低能有效理论,找到了这些模型的替代版本,给出了普适3-3-1模型及其翻转版本的新中性规范玻色子,并研究了左右对称模型及其翻转变体。我们的分析表明,有两个翻转版本的通用3-3-1模型,与特殊的是,他们都有相同的弱电荷。对于左右对称模型,我们还发现了两个翻转的版本;其中一个是文献中的新版本,与3-3-1不同,需要专门研究其电弱性质。对于所有的模型分析,$Z'$玻色子的标准模型费米子的耦合报告。给出了任意希格斯张量和规范群的矢量玻色子质量矩阵的零空间的显式形式。在$[SU(3)]^3$规范群的一般框架下,利用LHC实验结果和EW精密数据,得到了关于$Z'$质量和$Z$与新规范玻色子$Z'$混合角的极限.一般结果要求在$10^{-3}$弧度和$M_{Z'}>$ 2.5 TeV范围内的非常小的混合角。

英文摘要:

By considering the 3-3-1 and the left-right symmetric models as low energy effective theories of the $SU(3)_C\otimes SU(3)_L\otimes SU(3)_R$~(for short $[SU(3)]^3$) gauge group, alternative versions of these models are found. The new neutral gauge bosons of the universal 3-3-1 model and its flipped versions are presented; also, the left-right symmetric model and its flipped variants are studied. Our analysis shows that there are two flipped versions of the universal 3-3-1 model, with the particularity that both of them have the same weak charges. For the left-right symmetric model we also found two flipped versions; one of them new in the literature which, unlike those of the 3-3-1, requires a dedicated study of its electroweak properties. For all the models analyzed, the couplings of the $Z'$ bosons to the standard model fermions are reported. The explicit form of the null space of the vector boson mass matrix for an arbitrary Higgs tensor and gauge group is also presented. In the general framework of the $[SU(3)]^3$ gauge group, and by using the LHC experimental results and EW precision data, limits on the $Z'$ mass and the mixing angle between $Z$ and the new gauge bosons $Z'$ are obtained. The general results call for very small mixing angles in the range $10^{-3}$ radians and $M_{Z'}>$ 2.5 TeV.
