The equalization of temperatures between our universe and mirror sectors is reached 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 Planck mass. This effect excludes multidimensional Planck masses smaller than the reheating temperature of the Universe in mirror matter models, impacting options in particle physics and cosmology. Multidimensional models with flat additional dimensions are constrained in maximum temperature due to the effect of KK-mode overproduction, with new constraints playing a role in models with hyperbolic additional space.
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 multidimensional Planck masses smaller than the reheating temperature of the Universe (similar to 10(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.
