Title: Searching for dark matter sterile neutrinos in the laboratory

Abstract

If the dark matter of the Universe is made of sterile neutrinos with mass in the keV region, it can be searched for with the help of x-ray satellites. We discuss the prospects of laboratory experiments that can be competitive and complementary to space missions. We argue that the detailed study of {beta} decays of tritium and other nuclei with the help of cold target recoil ion momentum spectroscopy can potentially enter into an interesting parameter range and even supersede the current astronomical bounds on the properties of the dark matter sterile neutrinos.

  • We propose a strategy for how to look for dark matter particles possessing a radiative decay channel and derive constraints on their parameters from observations of x rays from our own Galaxy and its dwarf satellites. When applied to sterile neutrinos in the keV mass range this approach gives a significant improvement to restrictions on neutrino parameters compared with previous works.
  • The simplest model that can accommodate a viable nonbaryonic dark matter candidate is the standard electroweak theory with the addition of right-handed (sterile) neutrinos. We consider a single generation of neutrinos with a Dirac mass [mu] and a Majorana mass [ital M] for the right-handed component. If [ital M][much gt][mu] (standard hot dark matter corresponds to [ital M]=0), then sterile neutrinos are produced via oscillations in the early Universe with energy density independent of [ital M]. However, [ital M] is crucial in determining the large scale structure of the Universe; for [ital M][similar to]100 eV, sterile neutrinos make an excellentmore » warm dark matter candidate.« less
  • The matter power spectrum at comoving scales of (1-40)h{sup -1} Mpc is very sensitive to the presence of Warm Dark Matter (WDM) particles with large free-streaming lengths. We present constraints on the mass of WDM particles from a combined analysis of the matter power spectrum inferred from the large samples of high-resolution high signal-to-noise Lyman-{alpha} forest data of Kim et al. (2004) and Croft et al. (2002) and the cosmic microwave background data of WMAP. We obtain a lower limit of m{sub WDM} > or approx. 550 eV (2{sigma}) for early decoupled thermal relics and m{sub WDM} > or approx.more » 2.0 keV (2{sigma}) for sterile neutrinos. We also investigate the case where in addition to cold dark matter a light thermal gravitino with fixed effective temperature contributes significantly to the matter density. In that case the gravitino density is proportional to its mass, and we find an upper limit m{sub 3/2} < or approx. 16 eV (2{sigma}). This translates into a bound on the scale of supersymmetry breaking, {lambda}{sub susy} < or approx. 260 TeV, for models of supersymmetric gauge mediation in which the gravitino is the lightest supersymmetric particle.« less
  • We present constraints on the mass of warm dark matter (WDM) particles from a combined analysis of the matter power spectrum inferred from the Sloan Digital Sky Survey Lyman-{alpha} flux power spectrum at 2.2<z<4.2, cosmic microwave background data, and the galaxy power spectrum. We obtain a lower limit of m{sub WDM}(greater-or-similar sign)10 keV (2{sigma}) if the WDM consists of sterile neutrinos and m{sub WDM}(greater-or-similar sign)2 keV (2{sigma}) for early decoupled thermal relics. If we combine this bound with the constraint derived from x-ray flux observations of the Coma cluster, we find that the allowed sterile neutrino mass is {approx}10 keVmore » (in the standard production scenario). Adding constraints based on x-ray fluxes from the Andromeda galaxy, we find that dark matter particles cannot be sterile neutrinos, unless they are produced by a nonstandard mechanism (resonant oscillations, coupling with the inflaton) or get diluted by a large entropy release.« less
