在对撞机上探测标准模型的一个紧急的$U(1)$扩展

Probing an emergent $U(1)$ extension of the Standard Model at colliders

Tran N. Hung, Cao H. Nam

摘要:

我们探讨了一个新的中性规范玻色子,出现在一个拓扑非平凡的时空结构探测的潜力,专注于它的耦合的费米子的标准模型。我们分析了目前的实验约束的新规范玻色子的质量和第五维的半径,使用LEP约束和LHC与140 $\text{fb}^{-1}$光度。此外,我们调查的间接搜索新的规范玻色子和歧视的其他假设的规范玻色子一样,在$U(1)_{B-L}$和$U(1)_R$模型预测通过研究向前向后,左-右,左-右-向前向后的不对称性。

英文摘要:

We explore the potential of probing for a new neutral gauge boson that emerges from a topologically nontrivial structure of spacetime, focusing on its couplings to the fermions of the Standard Model. We analyze the current experimental constraints on the mass of the new gauge boson and the radius of the fifth dimension, using the LEP bound and the LHC with 140 $\text{fb}^{-1}$ luminosity. In addition, we investigate the indirect search of the new gauge boson and its discrimination from other hypothetical gauge bosons like those predicted in the $U(1)_{B-L}$ and $U(1)_R$ models by studying the forward-backward, left-right, and left-right-forward-backward asymmetries.
