Self–Interacting Dark Matter from the Hidden Heterotic–String Sector
It has been suggested recently that self–interacting dark matter fits better the observational characteristics of galaxy dynamics. We propose that the self–interacting dark matter is composed from the glueballs of the hidden sector non–Abelian gauge group, while the hidden matter states exist in vector–like representation and decouple from the light spectrum. It is shown that these glueballs ar...
متن کاملSelf-interacting dark matter from a non-Abelian hidden sector
There is strong evidence in favor of the idea that dark matter is self interacting, with the cross section-tomass ratio σ=m ∼ 1 cm=g ∼ 1 barn=GeV. We show that viable models of dark matter with this large cross section are straightforwardly realized with non-Abelian hidden sectors. In the simplest of such models, the hidden sector is a pure gauge theory, and the dark matter is composed of hidde...
متن کاملSelf-Interacting Dark Matter
Spergel and Steinhardt have recently proposed the concept of dark matter with strong self-interactions as a means to address numerous discrepancies between observations of dark matter halos on subgalactic scales and the predictions of the standard collisionless dark matter picture. We review the motivations for this scenario and discuss some recent, successful numerical tests. We also discuss t...
متن کاملMirror Matter as Self Interacting Dark Matter
It has been argued that the observed core density profile of galaxies is inconsistent with having a dark matter particle that is collisionless and alternative dark matter candidates which are self interacting may explain observations better. One new class of self interacting dark matter that has been proposed in the context mirror universe models of particle physics is the mirror hydrogen atom ...
