Axino as Cold Dark Matter Candidate
The possibility of the CDM axino is presented. From the early days of supersymmetry, axino has been considered as hot dark matter and warm dark matter. But the CDM axino has been considered quite recently. It is because the low reheating temperature of the universe is gaining momentum recently from various considerations in particle cosmology. I present a general introduction on the CDM’s, in p...
متن کاملLSP as a Candidate for Dark Matter
The most recent observations by the WMAP satellite provided us with data of unprecedented accuracy regarding the parameters describing the Standard Cosmological Model. The current matter-energy density of the Universe is close to its critical value of which 73 % is attributed to Dark Energy, 23 % to Cold Dark Matter and only 4 % is ordinary matter of baryonic nature. The origins of the Dark Ene...
متن کاملMixed dark matter with low-mass bosons.
We calculate the linear power spectrum for a range of mixed dark matter (MDM) models assuming a massive (few eV) boson, φ, instead of a neutrino as the hot component. We consider both the case where the hot dark matter (HDM) particle is a boson and the cold component is some other unknown particle, and the case where there is only one dark matter particle, a boson, with the cold dark matter (CD...
متن کاملFuzzy cold dark matter: the wave properties of ultralight particles.
Cold dark matter (CDM) models predict small-scale structure in excess of observations of the cores and abundance of dwarf galaxies. These problems might be solved, and the virtues of CDM models retained, even without postulating ad hoc dark matter particle or field interactions, if the dark matter is composed of ultralight scalar particles (m approximately 10(-22) eV), initially in a (cold) Bos...
متن کاملDetecting Ultralight Bosonic Dark Matter via Absorption in Superconductors
Superconducting targets have recently been proposed for the direct detection of dark matter as light as a keV, via elastic scattering off conduction electrons in Cooper pairs. Detecting such light dark matter requires sensitivity to energies as small as the superconducting gap of O(meV). Here we show that these same superconducting devices can detect much lighter DM, of meV to eV mass, via dark...
