Dark Matter Freeze-out during $\mathrm{SU}(2)_{\rm L}$ Confinement

Understand

We explore the possibility that dark matter is a pair of vector-like fermionic $\mathrm{SU}(2)_{\rm L}$ doublets and propose a novel mechanism of dark matter production that proceeds through the confinement of the weak sector of the Standard Model.

• This confinement phase causes the Standard Model doublets and dark matter to confine into pions.
• The dark pions freeze-out before the weak sector deconfines and generate a relic abundance of dark matter.
• We solve the Boltzmann equations for this scenario to determine the scale of confinement and constituent dark matter mass required to produce the observed relic density.
