Composite Dark Matter from Strongly-Interacting Chiral Dynamics
  A class of chiral gauge theories is studied with accidentally-stable pseudo
Nambu-Goldstone bosons playing the role of dark matter (DM). The gauge group
contains a vector-like dark color factor that confines at energies larger than
the electroweak scale, and a ${\rm U}(1)_D$ factor that remains weakly coupled
and is spontaneously broken. All new scales are generated dynamically,
including the DM mass, and the IR dynamics is fully calculable. We analyze
minimal models of this kind with dark fermions transforming as non-trivial
vector-like representations of the Standard Model (SM) gauge group. In
realistic models, the DM candidate is a SM singlet and comes along with charged
partners that can be discovered at high-energy colliders. The phenomenology of
the lowest-lying new states is thus characterized by correlated predictions for
astrophysical observations and laboratory experiments.
