Mixed dark matter with neutrino chemical potentials.
نویسندگان
چکیده
Mixed dark matter models with one low-mass (e.g. 2.4eV) neutrino avor are shown to be in good agreement with observations if the neutrinos have nonzero chemical potentials. This agreement holds (except for the problem with a low-age Universe) even for high values of the Hubble-parameter. Massless neutrinos with non-zero chemical potentials may reconcile cold dark matter with observations. Some ne-tuning is required to avoid problems with Big Bang nucleosynthesis. 14.60.Pq, 95.35.+d, 98.65.-r, 98.80.-k Physical Review D52 (in press) Typeset using REVT E X

Neutrino Masses in Astroparticle Physics
The case for small neutrino mass differences from atmospheric and solar neutrino oscillation experiments has become compelling, but leaves the overall neutrino mass scale mν undetermined. The most restrictive limit of mν < 0.8 eV arises from the 2dF galaxy redshift survey in conjunction with the standard theory of cosmological structure formation. A relation between the hot dark matter fraction...
متن کاملPower Spectra for Cold Dark Matter and its Variants
The bulk of recent cosmological research has focused on the adiabatic cold dark matter model and its simple extensions. Here we present an accurate tting formula that describes the matter transfer functions of all common variants, including mixed dark matter models. The result is a function of wavenumber, time, and six cosmological parameters: the massive neutrino density, number of neutrino sp...
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 کاملMixed Inert Scalar Triplet Dark Matter, Radiative Neutrino Masses and Leptogenesis
The neutral component of an inert scalar multiplet with hypercharge can provide a stable dark matter particle when its real and imaginary parts have a splitting mass spectrum. Otherwise, a tree-level dark matter-nucleon scattering mediated by the Z bo-son will be much above the experimental limit. In this paper we focus on a mixed inert scalar triplet dark matter scenario where a complex scalar...
متن کاملHigher order corrections to the large scale matter power spectrum in the presence of massive neutrinos
We present the first systematic derivation of the one-loop correction to the large scale matter power spectrum in a mixed cold+hot dark matter cosmology with subdominant massive neutrino hot dark matter. Starting with the equations of motion for the density and velocity fields, we derive perturbative solutions to these quantities and construct recursion relations for the interaction kernels, no...
