论文摘要
我们提出了一个新场景,暗物质属于一个僻静的部门,该部门通过能量量张量与标准模型耦合。我们的模型是由重力{\}从隐藏扇区出现的构造的动机,重力是由僻静部门中田地的动力学项所识别的。假设僻静部门的较轻粒子是宇宙的黑暗组成部分,我们表明,尽管该理论的抑制耦合被抑制了,但由于宇宙早期的热浴温度较大,我们仍可以以足够大量的量生产它。
We propose a new scenario where dark matter belongs to a secluded sector coupled to the Standard Model through energy--momentum tensors. Our model is motivated by constructions where gravity {\it emerges} from a hidden sector, the graviton being identified by the kinetic term of the fields in the secluded sector. Supposing that the lighter particle of the secluded sector is the dark component of the Universe, we show that we can produce it in a sufficiently large amount despite the suppressed couplings of the theory, thanks to large temperatures of the thermal bath in the early stage of the Universe.
