论文摘要
为了解决$μ$问题并在MSSM中产生三个小中微子质量，$ν$ supersymmmetric Standard Model（$μν$ SSM）的$μ$引入了三个Singlet右手中微子超级领域，从而导致Higgs Replotet与Sneutrinos的混合。混合会影响最轻的希格斯玻色子质量和希格斯耦合。目前观察到的95 \％Cl上限对125 GEV Higgs玻色子衰变的信号强度$ H \ rightarrowZγ$为6.6，这仍然很大，可以证明存在新物理学的存在。在这项工作中，我们研究了$μν$ SSM中125 GEV Higgs玻色子衰减通道$ H \ rightarrowZγ$的信号强度。此外，我们考虑了模型中MUON异常的磁偶极矩（MDM）的两环电动校正，这与一环电动校正相比也做出了重要的贡献。
To solve the $μ$ problem and generate three tiny neutrino masses in the MSSM, the $μ$ from $ν$ Supersymmetric Standard Model ($μν$SSM) introduces three singlet right-handed neutrino superfields, which lead to the mixing of the Higgs doublets with the sneutrinos. The mixing affects the lightest Higgs boson mass and the Higgs couplings. The present observed 95\% CL upper limit on signal strength of the 125 GeV Higgs boson decay $h\rightarrow Zγ$ is 6.6, which still is plenty of space to prove the existence of new physics. In this work, we investigate the signal strength of the 125 GeV Higgs boson decay channel $h\rightarrow Zγ$ in the $μν$SSM. Besides, we consider the two-loop electroweak corrections of muon anomalous magnetic dipole moment (MDM) in the model, which also make important contributions compared with one-loop electroweak corrections.
