Asymmetric Matters from a Dark First-Order Phase Transition

Eleanor Hall, Thomas Konstandin, Robert McGehee & Hitoshi Murayama
We introduce a model for matters-genesis in which both the baryonic and dark matter asymmetries originate from a first-order phase transition in a dark sector with an $SU(3) \times SU(2) \times U(1)$ gauge group and minimal matter content. In the simplest scenario, we predict that dark matter is a dark neutron with mass either $m_n = 1.33$ GeV or $m_n = 1.58$ GeV. Alternatively, dark matter may be comprised of equal numbers of dark protons...
