Particle Candidates for Dark Matter

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...

Dark 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 ...

Dark 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...

Scalar 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...
