“…This is very similar to the SuperWIMP scenario (see [29] for non-WIMP dark matter) except for the scale of the NLKP lifetime. The decay width of a typical SuperWIMP is suppressed by the Planck mass while in our case, it is suppressed by the small Yukawa coupling in the neutrino sector.…”

Split-UED allows for the possibility that the lowest lying KK excitations of the Standard Model fermions can be much lighter than the corresponding gauge or Higgs KK states. This can happen provided the fermion bulk masses are chosen to be large, in units of the inverse compactification radius, 1/R, and negative. In this setup, all of the other KK states would be effectively decoupled from low energy physics. Such a scenario would then lead to an apparent vector-like fourth generation with an associated discrete symmetry that allows us to accommodate a dark matter candidate. In this paper the rather unique phenomenology presented by this picture will be examined.

“…The most famous and well-studied example of WIMP dark matter is the neutralino in supersymmetry (Goldberg, 1983). Dark matter candidates also arise from theories of universal extra dimensions (Cheng et al, 2002;Hooper and Profumo, 2007), as well as many others (Duffy and van Bibber, 2009;Feng, 2010b) (see the recent reviews of Bertone et al (2005) and Bertone (2010) for a more complete list of dark matter candidates). In many cases these theories can be appealing not only from the perspective of having a well-motivated dark matter candidate, but also because they are often linked to various other unsolved problems in high energy physics, such as the stabilization of the Higgs mass, the unification of the forces at the GUT scale, or the explanation of the matterantimatter asymmetry.…”

Galactic searches for dark matter

For nearly a century, more mass has been measured in galaxies than is contained in the luminous stars and gas. Through continual advances in observations and theory, it has become clear that the dark matter in galaxies is not comprised of known astronomical objects or baryonic matter, and that identification of it is certain to reveal a profound connection between astrophysics, cosmology, and fundamental physics. The best explanation for dark matter is that it is in the form of a yet undiscovered particle of nature, with experiments now gaining sensitivity to the most well-motivated particle dark matter candidates. In this article, I review measurements of dark matter in the Milky Way and its satellite galaxies and the status of Galactic searches for particle dark matter using a combination of terrestrial and space-based astroparticle detectors, and large scale astronomical surveys. I review the limits on the dark matter annihilation and scattering cross sections that can be extracted from both astroparticle experiments and astronomical observations, and explore the theoretical implications of these limits. I discuss methods to measure the properties of particle dark matter using future experiments, and conclude by highlighting the exciting potential for dark matter searches during the next decade, and beyond.

“…The efforts in this direction have been recently and thoroughly reviewed, noting, e.g., Refs. [12,13,14,15,16]. Nevertheless, very recent experimental results and observational measurements suggest important shifts in perspective which this review imbues.…”

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 candidatesdark-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.
