A generalized Higgs potential with two degenerate minima for a dark QCD
  matter scenario
  We consider the Higgs potential in generalizations of the Standard Model. The
possibility of the potential to develop two almost degenerate minima is
explored. This would imply that QCD matter at two distinct sets of quark masses
is relevant for astrophysics and cosmology. If in the exotic minimum the QCD
matter ground state is electromagnetically neutral, dark matter may consist of
QCD matter and antimatter in bubbles of the Higgs field. We predict an
abundance of gamma rays in the few MeV region as messengers of dark matter
regions in space. In addition the ratio of dark matter to normal matter is
expected to show a time dependence.
