Particle Dark Matter
There is plenty of evidence that most matter in the universe is dark (non–luminous). Particle physics offers several possible explanations. In this talk I focus on cold dark matter; the most promising candidates are then axions and the lightest supersymmetric particle. I briefly summarize estimates for the present relic density of these particles, and describe efforts to detect them. To appear ...
متن کاملDark Matter Candidates from Particle Physics and Methods of Detection
The identity of dark matter is a question of central importance in both astrophysics and particle physics. In the past, the leading particle candidates were cold and collisionless, and typically predicted missing energy signals at particle colliders. However, recent progress has greatly expanded the list of well-motivated candidates and the possible signatures of dark matter. This review begins...
متن کاملParticle components of dark matter.
Particle candidates for astrophysical dark matter are reviewed, with particular emphasis on the lightest supersymmetric particle and the axion. The former is now constrained by accelerator experiments to have a mass above about 40 GeV, and ongoing searches at accelerators, in space, and in underground experiments have a good chance to detect it. A reevaluation of the constraint on the axion fro...
متن کاملGalactic halo models and particle dark-matter detection
Rates for detection of weakly interacting massive-particle ~WIMP! dark matter are usually carried out assuming the Milky Way halo is an isothermal sphere. However, it is possible that our halo is not precisely spherical; it may have some bulk rotation; and the radial profile may differ from that of an isothermal sphere. In this paper, we calculate detection rates in observationally consistent a...
متن کاملDark Matter and Particle Physics
Astrophysicists now know that 80% of the matter in the universe is ‘dark matter’, composed of neutral and weakly interacting elementary particles that are not part of the Standard Model of particle physics. I will summarize the evidence for dark matter. I will explain why I expect dark matter particles to be produced at the CERN LHC. We will then need to characterize the new weakly interacting ...
