Higgs反常中介中的分裂质谱和μ介子g-2

Splitting Mass Spectra and Muon g-2 in Higgs-Anomaly Mediation

Wen Yin, Norimi Yokozaki

摘要:

我们提出了一个方案,只有希格斯多重态有直接耦合到一个超对称性(SUSY)打破部门。标准模型的物质多重态以及规范多重态都被隔离在超对称性破裂扇区之外,因此,它们的质量是通过异常调解在高能尺度下产生的,引力子质量为$\sim$ 100 TeV。由于Higgs软质量的重整化群运行效应,第三代sfermion的质量在低能标度下变为O(10)TeV,而第一代和第二代sfermion的质量为O(0.1-1)TeV,避免了快子slepton问题和味变中性流问题.用分裂的质量谱,μ介子g-2的异常与观测到的125 GeV的希格斯玻色子质量一致。此外,第三代汤川耦合有望在某些区域得到统一。

英文摘要:

We propose a scenario where only the Higgs multiplets have direct couplings to a supersymmetry (SUSY) breaking sector. The standard model matter multiplets as well as the gauge multiples are sequestered from the SUSY breaking sector; therefore, their masses arise via anomaly mediation at the high energy scale with a gravitino mass of $\sim$100 TeV. Due to renormalization group running effects from the Higgs soft masses, the masses of the third generation sfermions become O(10) TeV at the low energy scale, while the first and second generation sfermion masses are O(0.1-1) TeV, avoiding the tachyonic slepton problem and flavor changing neutral current problem. With the splitting mass spectrum, the muon g-2 anomaly is explained consistently with the observed Higgs boson mass of 125 GeV. Moreover, the third generation Yukawa couplings are expected to be unified in some regions.
