轻Higgsino作为$μ$ - $B_μ$溶液的尾部

Light Higgsino as the tail of the $μ$-$B_μ$ solution

Masaki Asano, Norimi Yokozaki

摘要:

规范调解预测10 TeV或更重的平方,因为这样一个沉重的停止是必要的,以解释所观察到的125 GeV希格斯玻色子质量没有一个大的三线性软质量项在最小的超对称标准模型。尽管LHC无法直接搜索如此高的尺度,规范中介也通过$μ$问题的简单而朴素的解决方案预测了一个层次结构$μ^2 \ll B_μ$。我们指出,这种简单和天真的方式产生的$μ$($B_μ$)长期工程的情况下,10 TeV或更重的squarks与信使B-条款(或超对称质量条款)之间的一个大统一体的关系略有突破。此外,从观测到的希格斯玻色子质量、相关耦合的微扰性以及避免超快子中微子和终止的条件,得到了希格斯诺质量的上界.结果表明,O(100)GeV的轻Higgsino是一个有希望的规范中介信号。

英文摘要:

Gauge mediation predicts 10 TeV or heavier squarks because such a heavy stop is required to explain the observed 125 GeV Higgs boson mass without a large trilinear soft mass term in the minimal supersymmetric standard model. Although such a high scale cannot be searched by the LHC directly, gauge mediation also predicts a hierarchy $μ^2 \ll B_μ$ by a simple and naive solution of the $μ$ problem. We point out that this simple and naive way of generating the $μ$ ($B_μ$) term works in the case of 10 TeV or heavier squarks with a slight breaking of a GUT relation among messenger B-terms (or supersymmetric mass terms). Furthermore, the upper bound on the Higgsino mass is obtained from the observed Higgs boson mass, perturbativity of a relevant coupling, and conditions avoiding tachyonic sneutrinos and stop. It turns out that the light Higgsino of O(100) GeV is a promising signal of gauge mediation.
