论文摘要
我们研究了两个Higgs Doublet模型,其额外风味取决于$ u(1)_x $ gauge对称性,其中$ z'$ boson互动可以通过选择适当的sm fermions来解释Atomki异常。对于解释Atomki异常的参数区域,我们获得了使用$ \ MATHCAL {O}(10)$ GEV质量的光标度玻色子,我们探索标量扇区以搜索允许的参数空间。然后,我们讨论了MUON和LEPTON风味的异常磁偶极矩,违反了我们模型的Yukawa耦合引起的过程。
We investigate a two Higgs doublet model with extra flavour depending $U(1)_X$ gauge symmetry where $Z'$ boson interactions can explain the Atomki anomaly by choosing appropriate charge assignment for the SM fermions. For parameter region explaining the Atomki anomaly we obtain light scalar boson with $\mathcal{O}(10)$ GeV mass, and we explore scalar sector to search for allowed parameter space. We then discuss anomalous magnetic dipole moment of muon and lepton flavour violating processes induced by Yukawa couplings of our model.
