微型黑洞的产生和蒸发作为镜像宇宙之间的联系
Production and evaporation of micro black holes as a link between mirror universes
摘要：
它表明，我们和镜像部门之间的温度均衡发生在一个哈勃时间，由于微观黑洞的生产和粒子碰撞蒸发，如果宇宙的温度是多维普朗克质量附近。这种效应排除了镜像物质模型中小于宇宙再加热温度（$\sim10^{13}$ GeV）的多维普朗克质量，因为原始核合成理论要求镜像世界的温度应该低于我们。特别是，如果我们宇宙中的暗物质是由镜像物质的重子代表的话，那么在大型强子对撞机中微观黑洞的诞生是不可能的。它排除了粒子物理学和宇宙学中一些可能共存的选项。由于Kaluza-Klein模式（KK模式）的过度生产效应，具有平坦附加维度的多维模型已经在最高温度下受到强烈约束。在这些模型中，再加热温度应该明显小于多维普朗克质量，所以我们在这种情况下的限制不是最重要的。新的约束在多维模型中发挥作用，其中KK模的频谱不会导致它们在早期宇宙中的过度生产，例如，在双曲附加空间的理论中。
英文摘要：
It is shown that the equalization of temperatures between our and mirror sectors occurs during one Hubble time due to microscopic black hole production and evaporation in particle collisions if the temperature of the Universe is near the multidimensional Plank mass. This effect excludes the multidimensional Planck masses smaller than the reheating temperature of the Universe ($\sim10^{13}$ GeV) in the mirror matter models, because the primordial nucleosynthesis theory requires that the temperature of the mirror world should be lower than ours. In particular, the birth of microscopic black holes in the LHC is impossible if the dark matter of our Universe is represented by baryons of mirror matter. It excludes some of the possible coexisting options in particle physics and cosmology. Multidimensional models with flat additional dimensions are already strongly constrained in maximum temperature due to the effect of Kaluza-Klein mode (KK-mode) overproduction. In these models, the reheating temperature should be significantly less than the multidimensional Planck mass, so our restrictions in this case are not paramount. The new constraints play a role in multidimensional models in which the spectrum of KK-modes does not lead to their overproduction in the early Universe, for example, in theories with hyperbolic additional space.
