Title: Astrophysical evidences of neutron-dark neutron connection
Abstract:
I discuss present situation in cosmic rays, regarding (1) the paradoxical situation in the spectrum, chemical content and isotropic distribution of the extreme energy cosmic rays (E>100 EeV) (2) AMS-2 observation of helium antinuclei in low energy cosmic rays which cannot be explained by standard and standard-like mechanisms. I discuss how these paradoxes could be resolved by hypothesis that dark matter consists of mirror matter, and the neutron can oscillate into mirror neutron with characteristic time of few seconds. This possibility does not contradict to present experimental limits on the neutron-mirror neutron oscillations.
