neutralino
1.Computation of Cosmic Ray Antiproton Spectrum from Neutralino Annihilation
2.The hypothesized mass, stability and neutrality of the neutralino satisfy all the requirements of cold dark matter.
3.As the name implies, the neutralino has zero charge, so it is unaffected by electromagnetic forces (such as those involving light).
4.In fact, based on the expected neutralino mass and its low tendency to collide, the total mass in neutralinos almost exactly matches the inferred mass of dark matter in the universe.
