具有伴随消息的规范中介模型

Gauge Mediation Models with Adjoint Messengers

Ilia Gogoladze, Azar Mustafayev, Qaisar Shafi, Cem Salih Un

摘要:

我们在规范中介超对称破缺的框架中提出了一类模型,其中信使场在标准模型规范对称性的伴随表示中变换。为了避免在光谱中出现不可接受的轻右旋slepton,我们引入了非零U(1)_B-L D项。这导致了对软超对称破缺质量项的额外贡献,这使得右手slepton质量与当前的实验边界相容。我们表明,在这个框架中,所观察到的125 GeV的希格斯玻色子玻色子质量可以容纳与slepton在大型强子对撞机访问,而在多TeV的范围内的夸克和胶子谎言。我们还讨论了微调的问题,并表明所需的遗物暗物质丰度也可以容纳。

英文摘要:

We present a class of models in the framework of gauge mediation supersymmetry breaking where the messenger fields transform in the adjoint representation of the Standard Model gauge symmetry. To avoid unacceptably light right-handed sleptons in the spectrum we introduce a non-zero U(1)_B-L D-term. This leads to an additional contribution to the soft supersymmetry breaking mass terms which makes the right-handed slepton masses compatible with the current experimental bounds. We show that in this framework the observed 125 GeV Higgs boson mass can be accommodated with the sleptons accessible at the LHC, while the squarks and gluinos lie in the multi-TeV range. We also discuss the issue of the fine-tuning and show that the desired relic dark matter abundance can also be accommodated.
