外尔对称激发了暴胀和暗物质

Weyl Symmetry Inspired Inflation and Dark Matter

Yong Tang, Yue-Liang Wu

摘要:

受外尔标度规范对称性的启发,我们提出了一个同时解释宇宙暴胀和暗物质的理论框架。这种对称性在最近的引力规范理论的尝试中又复活了。我们发现,灵感膨胀模型与目前的观测结果是一致的,并将进一步探讨未来的实验。进一步阐明并证明了Weyl规范玻色子在多标量一般理论中的稳定性。我们表明,大量的外尔规范玻色子可以是一个暗物质的候选人,并给出正确的遗迹丰度。

英文摘要:

Motivated by the Weyl scaling gauge symmetry, we present a theoretical framework to explain cosmic inflation and dark matter simultaneously. This symmetry has been resurrected in recent attempts to formulate the gauge theory of gravity. We show the inspired inflation model is well consistent with current observations and will be probed further by future experiments. Furthermore, we clarify and prove the stability of Weyl gauge boson in the general theory with multiple scalars. We show the massive Weyl gauge boson can be a dark matter candidate and give the correct relic abundance.
