Production and evaporation of micro black holes as a link between mirror universes

Abstract

It is shown that the equalisation of temperatures between our and mirror sectors occurs during one Hubble time due to microscopic black holes production and evaporation in particles collisions if the temperature of the universe is near the multidimensional Plank mass. This effect excludes the multidimensional Planck masses smaller then the reheating temperature of the universe (∼ 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 the ours. In particular, the birth of microscopic black holes on the LHC is impossible if the dark matter of our universe is represented by baryons of mirror matter. It excludes some of the possible co-existing options in particle physics and cosmology.
