3-4-1模型能解释即将出现的μ子反常磁矩结果吗?

Are 3-4-1 models able to explain the upcoming results of the muon anomalous magnetic moment?

摘要:

鉴于即将进行的μ子反常磁矩(g-2)的测量,我们在$SU(4)_L \times U(1)_X$规范对称性的背景下重新讨论了g-2的修正。我们调查三个模型的基础上,这种规范对称性和表达我们的结果在能量尺度的$SU(4)_L \times U(1)_X$对称性被打破。为了得出可靠的结论,我们将我们的发现与现有的对撞机界限相结合。最后,我们强调我们的结果和那些从$SU(3)_L \times U(1)_X$结构上升之间的差异。

英文摘要:

In light of the upcoming measurement of the muon anomalous magnetic moment (g-2), we revisit the corrections to g-2 in the context of the $SU(4)_L \times U(1)_X$ gauge symmetry. We investigate three models based on this gauge symmetry and express our results in terms of the energy scale at which the $SU(4)_L \times U(1)_X$ symmetry is broken. To draw solid conclusions we put our findings into perspective with existing collider bounds. Lastly, we highlight the difference between our results and those rising from $SU(3)_L \times U(1)_X$ constructions.
