一个完整的小尺度规范调解模型

A Complete Model of Low-Scale Gauge Mediation

Nathaniel Craig, Simon Knapen, David Shih, Yue Zhao

摘要:

最近的迹象表明,一个标准模型,像希格斯粒子在125 GeV指向大的A-项在MSSM。这对规范中介提出了特殊的挑战,规范中介本身就预测了信使尺度上A项的消失。在本文中,我们回顾了扩展规范调解时出现的一般问题,以实现大的A-条款,并存在克服它们的机制。利用这些机制,我们构建了弱耦合模型的低尺度规范调解与扩展希格斯信使耦合,产生大的A项在信使尺度和可行的mu/B_mu项。我们的模型是简单,经济,和完整的实现超对称性在弱标度。

英文摘要:

Recent signs of a Standard Model-like Higgs at 125 GeV point towards large A-terms in the MSSM. This presents special challenges for gauge mediation, which by itself predicts vanishing A-terms at the messenger scale. In this paper, we review the general problems that arise when extending gauge mediation to achieve large A-terms, and the mechanisms that exist to overcome them. Using these mechanisms, we construct weakly-coupled models of low-scale gauge mediation with extended Higgs-messenger couplings that generate large A-terms at the messenger scale and viable mu/B_mu-terms. Our models are simple, economical, and complete realizations of supersymmetry at the weak scale.
