希格斯信使

General Messenger Higgs Mediation

Nathaniel Craig, Simon Knapen, David Shih

摘要:

我们提出了一个一般的形式主义分析超对称模型,希格斯部门直接耦合到超对称破缺的信使。在125 GeV附近发现的希格斯玻色子玻色子强烈地激发了这种希格斯-信使相互作用,但它们也引发了mu/B_mu和A/m_H^2问题的幽灵。使用我们的形式主义,我们通过信使部门或隐藏部门的强大动力来确定解决这些问题的新途径。尽管我们的形式主义是完全通用的,但我们展示了它如何在两个简化限制中重现熟悉的结果:一个是隐藏扇区由单个spurion组成,另一个是近似超共形的。在后一个极限中,我们的形式主义概括和澄清了隐藏扇区隔离的情况,我们表明它可以统一解决mu/B_mu和A/m_H^2问题。

英文摘要:

We present a general formalism for analyzing supersymmetric models where the Higgs sector directly couples to the messengers of supersymmetry breaking. Such Higgs-messenger interactions are strongly motivated by the discovery of a Higgs boson near 125 GeV, but they also raise the specter of the mu/B_mu and A/m_H^2 problems. Using our formalism, we identify new avenues to solving these problems through strong dynamics in the messenger sector or hidden sector. Although our formalism is entirely general, we show how it reproduces familiar results in two simplifying limits: one where the hidden sector consists of a single spurion, and the other where it is approximately superconformal. In the latter limit, our formalism generalizes and clarifies the scenario of hidden sector sequestering, which we show can solve both the mu/B_mu and A/m_H^2 problems uniformly.
