A scenario of heavy but visible baryonic dark matter

Understand

We consider a model in which dark matter is a composite baryon of a dark sector governed by $SU(3)$ gauge theory, with vector-like quarks also charged under $U(1)_Y$.

• The model provides simple answer to the dark matter stability problem: it is a result of the accidental dark baryon number conservation.
• And with an analogy to QCD, all physical quantities of the dark matter can be calculated by rescaling the QCD experimental results.
• According to the thermal freeze-out mechanism the mass of the dark matter is predicted to be $\mathcal{O}(100)$~TeV in order to achieve a correct relic abundance.
