论文摘要
一个新的重型$ z'$ vector Boson为中性当前B异常提供了一个可能的解释，并指向规模，我们希望解决层次结构问题的解决方案。在本文中，我们基于$ u（3）_l $ to $ u（2）_l $的全局对称性破坏的全局对称性破坏。对称性的部分被衡量，使破坏不仅引入了复合希格斯双线，而且还引入了TEV规模的$ z'$ boson。 $ u（3）_l/u（2）_l $ top seeSaw模型预测了一个轻型的higgs玻色子以及大型顶部的Yukawa耦合。额外的$ u（1）'$对称性被衡量，因此引入了一个美味的TEV尺度$ Z'Ubobon，以解决B异常。 CDF协作所观察到的，这种类似重型矢量的顶级夸克和$ z-Z'$混合的存在破坏了托管对称性，该对称性预测较重的$ w $质量。详细讨论了$ u（1）'$对称的两个可能的候选人，与$ z'$ boson相对应，$ u（1）_l $和$ u（1）_ {l-r} $。提出了用于解决两个异常的模型的参数空间。还研究了Dilepton频道的$ z'ub -Boson的直接搜索。根据假设，TEV规模的$ Z'$ Boson仍然可行，可以在不久的将来进行探测。
A new heavy $Z'$ vector boson provides a possible explanation for the neutral current B anomalies and points to the scale where we expect the solution to the hierarchy problem to appear. In this paper, we explore a modified Top Seesaw model based on the global symmetry breaking of $U(3)_L$ to $U(2)_L$. The symmetry is partially gauged such that the breaking introduces not only a composite Higgs doublet but also a TeV-scale $Z'$ boson. The $U(3)_L/U(2)_L$ Top Seesaw model predicts a light Higgs boson as well as a large top Yukawa coupling. Additional $U(1)'$ symmetry is gauged such that a flavorful TeV-scale $Z'$ boson is introduced to address the B anomalies. The existence of a heavy vector-like top quark and $Z-Z'$ mixing breaks the custodial symmetry, which predicts a heavier $W$ mass as observed by the CDF collaboration. Two possible candidates for the $U(1)'$ symmetry corresponding to the $Z'$ boson, $U(1)_L$ and $U(1)_{L-R}$, are discussed in detail. The parameter space for the models to address both anomalies is presented. The direct searches of the $Z'$ boson from dilepton channels are also studied. Based on the assumptions, a TeV-scale $Z'$ boson is still viable and can be probed in the near future.
