Grand unified dark matter

Presented by Mr. Stephen LONSDALE on 25 Jul 2014 from 15:10 to 15:30
Type: Alternative Theories
Track: Alternative Theories


Asymmetric dark matter models are useful in providing an explanation for the number density of dark matter in the universe but typically do not provide an explanation for the mass of dark matter particles. In this talk I discuss the capacity for unified models to solve this problem by linking the confinement scales of baryons in visible and dark sectors to each other through the condition of unified coupling constants. By examining the dependence of the QCD scale on fermion masses and symmetry breaking scales in both SUSY and non-SUSY GUT models, we can examine a wide range of unified models of two sectors paired under a discrete symmetry and which break asymmetrically, generating a final SU(3) confining gauge theory in each sector that yields similar but different masses for visible and dark baryons. It can then be demonstrated that this asymmetric breaking works in an SU(5)XSU(5) case and that we can acquire a dark QCD scale just above that of the standard model. I will finally discuss how we can adopt this approach in supersymmetric theories and explore the possibility of larger GUT candidates.
