Motivated by the observed ratio of dark matter to baryon mass densities, ρD/ρB ' 5, we propose a theory of dark-color unification. In this theory, the dark to visible baryon masses are fixed by the ratio of dark to visible confinement scales, which are determined to be nearby in mass through the unification of the dark and visible gauge theories at a high scale. Together with a mechanism for darko-baryo-genesis, which arises naturally from the grand unification sector, the mass densities of the…

Self-interacting dark baryons
• Physics
• 2022
Using results from lattice QCD, it is possible to quantitatively design models of dark baryons leading to velocity-dependent self-interaction cross sections that match the values needed for solving

The Status of Glueballs
Calculations within QCD (lattice and sum rules) find the lightest glueball to be a scalar with mass in the range of about 1000–1700 MeV. Several phenomenological investigations are discussed which

We consider an enlarged color sector which solves the strong CP problem via new massless fermions. The spontaneous breaking of a unified color group into QCD and another confining group provides a
Abelian hidden sectors at a GeV
• Physics
• 2009
We discuss mechanisms for naturally generating GeV-scale hidden sectors in the context of weak-scale supersymmetry. Such low mass scales can arise when hidden sectors are more weakly coupled to
Dark matter from one-flavor SU(2) gauge theory
• Physics
• 2016
SU(2) gauge theory with a single fermion in the fundamental representation is a minimal non-Abelian candidate for the dark matter sector, which is presently missing from the standard model. Having
Robust implications on dark matter from the first FERMI sky γ map
• Physics

We derive robust model-independent bounds on Dark Matter (DM) annihilations and decays from the first year of FERMI ?-ray observations of the whole sky. These bounds only have a mild dependence on

Abstract. We present the final results obtained by the MACRO experiment in the search for GUT magnetic monopoles in the penetrating cosmic radiation, for the range $4\times 10^{-5}< \beta < 1$.
