Dark Matter in Very Supersymmetric Dark Sectors
  If supersymmetry exists at any scale, regardless of whether it is restored
around the weak scale, it may be a good symmetry of the dark sector, enforcing
a degeneracy between its lowest lying fermions and bosons. We explore the
implications of this scenario for the early universe and dark matter, as well
as the corresponding signatures. In particular we show that the thermal history
of the dark sector results in co-decaying dark matter in much of the parameter
space. This implies new phenomenological signatures and presents a new way to
discover high scale supersymmetry.
