Query: Asymmetric Dark Matter in Extended Exo-Higgs Scenarios   The exo-Higgs model can accommodate a successful baryogenesis mechanism that
closely mirrors electroweak baryogenesis in the Standard Model, but avoids its
shortcomings. We extend the exo-Higgs model by the addition of a singlet
complex scalar $\chi$. In our model, $\chi$ can be a viable asymmetric dark
matter (ADM) candidate. We predict the mass of the ADM particle to be
$m_\chi\approx1.3\, \textrm{GeV}$. The leptophilic couplings of $\chi$ can
provide for efficient annihilation of the ADM pairs. We also discuss the LHC
signals of our scenario, and in particular the production and decays of
exo-leptons which would lead to "lepton pair plus missing energy" final states.
Our model typically predicts potentially detectable gravitational waves
originating from the assumed strong first order phase transition at a
temperature of $\sim$ TeV. If the model is further extended to include new
heavy vector-like fermions, {\it e.g.} from an ultraviolet extension, $\chi$
couplings could explain the $\sim 3.5\sigma $ muon $g-2$ anomaly.
