10 Jul 2002 | | Journal: | Phys.Rev.Lett. 89 (2002) 211301 | | Subject: | hep-ph astro-ph hep-ex | | Abstract: | We propose that cold dark matter is made of Kaluza-Klein particles and explore avenues for its detection. The lightest Kaluza-Klein state is an excellent dark matter candidate if standard model particles propagate in extra dimensions and Kaluza-Klein parity is conserved. We consider Kaluza-Klein gauge bosons. In sharp contrast to the case of supersymmetric dark matter, these annihilate to hard positrons, neutrinos and photons with unsuppressed rates. Direct detection signals are also promising. These conclusions are generic to bosonic dark matter candidates. | | Source: | arXiv, hep-ph/0207125 | | Other source: | [GID 960113] pmid12443401 | | Services: | Forum | Review | PDF | Favorites | |
