Dark Matter Studies Entrain Nuclear Physics
  We review theoretically well-motivated dark-matter candidates, and pathways
to their discovery, in the light of recent results from collider physics,
astrophysics, and cosmology. Taken in aggregate, these encourage broader
thinking in regards to possible dark-matter candidates --- dark-matter need not
be made of "WIMPs," i.e., elementary particles with weak-scale masses and
interactions. Facilities dedicated to nuclear physics are well-poised to
investigate certain non-WIMP models. In parallel to this, developments in
observational cosmology permit probes of the relativistic energy density at
early epochs and thus provide new ways to constrain dark-matter models,
provided nuclear physics inputs are sufficiently well-known. The emerging
confluence of accelerator, astrophysical, and cosmological constraints permit
searches for dark-matter candidates in a greater range of masses and
interaction strengths than heretofore possible.
