我们探索了在Z2对称下可见扇区和隐藏扇区或暗扇区配对的GXG统一理论。我们开发了一个“不对称破缺”的系统，我们根据这些模型产生暗重子的能力来激励它们，这些暗重子的质量尺度仅高于质子的质量尺度，这是由不对称暗物质驱动的。这种差异是从统一理论中发展起来的不同但相关的限制标度实现的，统一理论具有两个因素，即$G$以不对称的方式自发破裂。我们展示了如何构造在每个扇区允许不同规范群断链的希格斯势，并证明了产生不同费米子质量标度的能力。最后，我们讨论了这类方案的超对称扩张。
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.
