论文摘要
超对称双HIGGS模型允许通过通过其他意外的全局对称性来保护希格斯玻色子的质量来减少微小超对称标准模型的微调。这类模型介绍了许多新州，其中一些可能是暗物质的候选人。由于这些人居住在双胞胎部门，因此不受标准模型量规组的收费。我们提议双胞胎作为暗物质的候选人。即使双stau在双电磁场下被收取，但由于超对称伙伴从超对称破裂中获得了大量群体，因此它们可以轻松地逃脱界限以进行自我相互作用的暗物质。重现正确的遗物丰度的双stau的质量通常在300至500 GEV之间。可以通过未来的直接检测实验（例如Lux-Zepelin）来探测这种情况。
Supersymmetric Twin Higgs models allow for reducing the fine-tuning with respect to Minimal Supersymmetric Standard Model by protecting the mass of the Higgs boson by additional, accidental global symmetry. This class of models introduce numerous new states, some of which might be candidates for dark matter. Since those reside in twin sector, they are not charged under Standard Model gauge group. We proposed twin stau as a candidate for dark matter. Even though twin stau is charged under twin electromagnetism, since supersymmetric partners obtain large masses from supersymmetry breaking they can easily escape bounds for self-interacting dark matter. The mass of twin stau which reproduces correct relic abundance is usually between 300 and 500 GeV. This scenario can be probed by future direct detection experiments such as Lux-Zepelin.
