论文摘要
在这项工作中，我们讨论了一个与众不同的$ pp \ to {\ rm higgs} \至z'z't to z'z't to 4l $（$ l = e，μ$）在大型强子对撞机（LHC）上的信号$ u（1）'$对称性除了标准型号（SM）仪表组。额外的$ u（1）'$对称会产生一个非常轻的$ z'$状态，矢量和轴向和轴向（非宇宙）耦合与费米子相结合，它们能够解释所谓的ATOMKI异常，并符合当前对电子和MUON和MUON电子和MUON和MUON和MUON和光束漏斗实验的异常磁矩（AMMS）的测量。我们表明，此过程的横截面应足够大，可以在LHC运行3期间具有显着灵敏度的一个横截面。
In this work, we discuss a distinctive $pp\to {\rm Higgs}\to Z'Z'\to 4l$ ($l=e,μ$) signal at the Large Hadron Collider (LHC), where the `Higgs' label refers to the SM-like Higgs state discovered in 2012 or a lighter one in the framework of a theoretical model embedding a spontaneously broken $U(1)'$ symmetry in addition to the Standard Model (SM) gauge group. The additional $U(1)'$ symmetry generates a very light $Z'$ state, with both vector and axial (non-universal) couplings to fermions, which are able to explain the so-called Atomki anomaly, compliant with current measurements of the Anomalous Magnetic Moments (AMMs) of electron and muon as well as beam dump experiments. We show that the cross section for this process should be sufficiently large to afford one with significant sensitivity during Run 3 of the LHC.
