论文摘要
如果Sleptons和Electroweak Gauginos为$ \ Mathcal {O}（100）$ GEV，SuperSymmetry仍然是MUON $ G-2 $异常的可行解释。然而，对于超对称性质量的质量，SUSY风味和CP问题会加剧。为了解决这个问题，我们考虑了对Muon $ G-2 $的风味安全量规介导的解释，并具有其他Higgs软性超对称性质量参数。该设置提供了最小规格中的通用参数空间。此外，我们表明违反CP的阶段可以动态抑制。我们发现，量规调子模型具有很大的参数空间，可以在1 $σ$级别上解释Muon $ G-2 $。 Shepton和CP-ODD Higgs质量之间的相互作用也使该模型的大部分参数空间可以通过搜索Sleptons或其他Higgs玻色子在LHC进行测试。
Supersymmetry is still a viable explanation for the muon $g-2$ anomaly, if the sleptons and electroweak gauginos are $\mathcal{O}(100)$ GeV. However, for supersymmetry breaking masses this light, the SUSY flavor and CP-problem are exacerbated. To address this issue, we consider a flavor-safe gauge mediated explanation of the muon $g-2$ with additional Higgs soft supersymmetry breaking mass parameters. The setup provides a generic parameter space within minimal gauge mediation. Furthermore, we show that the problematic CP violating phase can be dynamically suppressed. We find that gauge mediation models have large portions of parameter space where the muon $g-2$ can be explained at 1 $σ$ level. The interplay between the slepton and the CP-odd Higgs masses also makes the majority of this model's parameter space testable at the LHC through searches for sleptons or additional Higgs bosons.
