Particle Dark Matter: Evidence, Candidates and Constraints
In this review article, we discuss the current status of particle dark matter, including experimental evidence and theoretical motivations. We discuss a wide array of candidates for particle dark matter, but focus on neutralinos in models of supersymmetry and Kaluza-Klein dark matter in models of universal extra dimensions. We devote much of our attention to direct and indirect detection techni...
متن کاملDark Matter Candidates
An overview is given of various dark matter candidates. Among the many suggestions given in the literature, axions, inert Higgs doublet, sterile neutrinos, supersymmetric particles and Kaluza-Klein particles are discussed. The situation has recently become very interesting with new results on antimatter in the cosmic rays having dark matter as one of the leading possible explanations. Problems ...
متن کاملScalar Dark Matter candidates
We investigate the possibility that Dark Matter could be made of scalar candidates and focus, in particular, on the unusual mass range between a few MeV’s and a few GeV’s. After showing why the Lee-Weinberg limit (which usually forbids a Dark Matter mass below a few GeV’s) does not necessarily apply in the case of scalar particles, we discuss how light candidates (mdm < O(GeV) ) can satisfy bot...
متن کاملCold Dark Matter Candidates
According to astrophysical and cosmological observations, about 20 percent of the total energy in the universe is contributed by dark matter, which, within present observational limits, only exhibits gravitational interaction. Meanwhile, the Standard Model of elementary particles don’t contain such weakly-interacting constituents. To solve this mystery several schemes extending the Standard Mod...
متن کاملDark Matter Candidates
It is now widely accepted that most of mass–energy in the universe is unobserved except by its gravitational effects. Baryons make only about 4% of the total, with “dark matter” making up about 23% and the “dark energy” responsible for the accelerated expansion of the universe making up the remainder. We focus on the dark matter, which is the primary constituent of galaxies. We outline the obse...
