Abstract

A brief review of the Mirror Matter (MM) model in modern pattern of the Dark Matter (DM) problem. This model was proposed by I.Yu.Kobzarev, L.B.Okun, and I.Ya.Pomeranchuk in 1966. Mirror Matter is the oldest but still viable candidate for the description of real DM, but probably not in the pure form. The difficulties of standard ΛCDM model with WIMPs (Weakly Interacting Massive Particles) are touched upon. It is shown where Mirror Matter could help in solving some of those problems. Mirror particles are a subclass of a wider set of ADM (Asymmetric DM, when DM particles do not annihilate contrary to supersymmetric particles in ΛCDM). The references on limits for cross-sections of bosons in ADM models accreting onto neutron stars are given. They can be much lower than experimental limits for WIMPs.
