Higgs boson emerging from the dark
  We propose a new non-thermal mechanism of dark matter production based on
vacuum misalignment. A global $X$-charge asymmetry is generated at high
temperatures, under which both the will-be Higgs and the dark matter are
charged. At lower energies, the vacuum changes alignment and breaks the
$U(1)_X$, leading to the emergence of the Higgs and of a fraction of charge
asymmetry stored in the stable dark matter relic. This mechanism can be present
in a wide variety of models based on vacuum misalignment, and we demonstrate it
in a composite Higgs template model, where all the necessary ingredients are
naturally present. A light pseudo-scalar $\eta$ is always predicted, with
interesting implications for cosmology, future supernova observations and
exotic $Z \to \gamma \eta$ decays.
