Abstract
I discuss the possibility of dark matter conversion into our antimatter, assuming that a part of dark matter is represented by a hypothetical mirror matter. In the Early Universe, [Formula: see text] and [Formula: see text] violating interactions between the particles of ordinary and mirror worlds can co-generate their baryon asymmetries in comparable amounts, [Formula: see text], also predicting the sign of mirror baryon asymmetry. At low energies, the same interactions induce particle mixing phenomena between two sectors. In this way, e.g. mirror neutron [Formula: see text] should oscillate into our antineutron [Formula: see text], with probability that depends on environmental conditions as matter density and magnetic fields. This oscillation can be faster than the neutron decay itself, with [Formula: see text] conversion rate accessible for the experimental search. It can have fascinating phenomenological and astrophysical consequences, and can potentially open an unlimited source of energy by transforming dark mirror matter into antimatter in a controllable way.
