大统一暗扇区暗物质

Grand unified hidden-sector dark matter

Stephen J. Lonsdale, Raymond R. Volkas

摘要:

我们探索GxG统一理论与Z2对称下配对的可见和隐藏或黑暗的部门。开发一个系统的“不对称对称性破缺”,我们激励这样的模型的基础上,他们的能力,以产生暗重子,被限制在一个质量尺度上的质子,不对称的暗物质的动机。这种差异是从不同的,但相关的限制尺度,发展在统一的理论,有两个因素的$G$自发打破一个不对称的方式。我们展示了如何希格斯的潜力,承认不同的规范组打破链在每个部门可以构建,并证明了产生不同的费米子质量尺度的能力。最后讨论了这类方案的超对称扩张。

英文摘要:

We explore GxG unified theories with the visible and the hidden or dark sectors paired under a Z2 symmetry. Developing a system of 'asymmetric symmetry breaking' we motivate such models on the basis of their ability to generate dark baryons that are confined with a mass scale just above that of the proton, as motivated by asymmetric dark matter. This difference is achieved from the distinct but related confinement scales that develop in unified theories that have the two factors of $G$ spontaneously breaking in an asymmetric manner. We show how Higgs potentials that admit different gauge group breaking chains in each sector can be constructed, and demonstrate the capacity for generating different fermion mass scales. Lastly we discuss supersymmetric extensions of such schemes.
