The scenario with hadronic dark matter

Abstract

In this paper, we analyze scenario with strongly interacting massive particles which follows from the Standard Model extension with singlet quark. The lightest new neutral hadron is stable, it can be interpreted as a candidate for hadronic dark matter. Here, we consider principal features of this scenario: large mass of new hadrons, fine and hyperfine splitting in the spectrum of hadron states, low-energy interaction with the standard particles. Both splitting effects lead to processes which can be registered in cosmic rays and deciphered as the hadronic dark matter manifestations. In this work, we reconsider and specify some results from our previous papers.
