Probably the likeliest candidate is the neutralino, which is a mixed eigenstate or condensate of the supersymmetric pairs of the photon, higgs and Z_0 particle.

Kane's personal bet for the particle behind dark matter in these findings is called a wino (pronounced WEE-no) - a specific type of neutralino, which is a theorized category of particles that could exist as "supersymmetric partners" for all the Standard Model particles such as electrons, quarks, etc.

It will begin to produce the goods next year with the possible discovery of a particle called a neutralino, which could reveal the nature of the mysterious dark matter that makes up about 23 per cent of the universe.

I suspect that some how DM halos in galaxy clusters do eventually coalesce into larger ones, and either decay, say by neutralino decays a supersymmetric field which might compose much of DM or eventually end up being consumed by the galactic black hole at the center.

The neutralino is about 1TeV in mass and so only about a milligram of DM would be absorbed.

-
The lightest sparticle (neutralino) is expected to be stable and fairly heavy (50 to 2000 GeV), so it is an ideal WIMP candidate.
-
The PAMELA detector and Fermi spacecraft found TeV gamma photon flux from the galactic center, in some agreement with neutralino annihilations.
-
The currently most favored WIMP candidate is a neutralino, a hypothetical particle predicted by supersymmetry theory.
-
If one were to set up a lot of particles in motion, maybe according to a hydro-code, then the evolution might clump some of this matter into the center with increased radiation production from neutralino annihilations and the eventual production of compact bodies towards the center.
