Title: Cosmological neutrino mass limit and the dynamics of dark energy

Abstract

We investigate the correlation between the neutrino mass limit and dark energy with the time evolving equation of state. Parametrizing dark energy as w=w{sub 0}+w{sub 1}*z/(1+z), we make a global fit using Markov Chain Monte Carlo technique to determine w{sub 0}, w{sub 1}, neutrino mass as well as other cosmological parameters simultaneously. We pay particular attention to the correlation between neutrino mass {sigma}m{sub {nu}} and w{sub 1} using current cosmological observations as well as the future simulated data sets such as PLANCK, SNAP, and LAMOST.

  • At present, cosmology provides the nominally strongest constraint on the masses of standard model neutrinos. However, this constraint is extremely dependent on the nature of the dark energy component of the Universe. When the dark energy equation of state parameter is taken as a free (but constant) parameter, the neutrino mass bound is (95% C.L.), compared with (95% C.L.) in the standard model where the dark energy is in the form of a cosmological constant. This has important consequences for future experiments aimed at the direct measurement of neutrino masses. We also discuss prospects for future cosmological measurements of neutrinomore » masses.« less
  • We show that considerations of the equilibration of right- and left-handed neutrino seas in the early Universe and the well-known {sup 4}He constraint on the number of relativistic degrees of freedom extant at the nucleosynthesis epoch lead to a new limit on the Dirac neutrino mass of {ital m}{sub {nu}}{much lt}300 keV. This constraint would apply to any neutrino so long as it had a purely Dirac mass and a lifetime exceeding the nucleosynthesis time scale.
  • Previous fits of sterile neutrino dark matter (DM) models to cosmological data ruled out masses smaller than {approx}8 keV, assuming a production mechanism that is not the best motivated from a particle physics point of view. Here we focus on a realistic extension of the standard model with three sterile neutrinos, consistent with neutrino oscillation data and baryogenesis, with the lightest sterile neutrino being the DM particle. We show that for each mass {>=}2 keV there exists at least one model accounting for 100% of DM and consistent with Lyman-{alpha} and other cosmological, astrophysical, and particle physics data.
  • We fit WMAP5 and related data by allowing for a CDM-DE coupling and non-zero neutrino masses, simultaneously. We find a significant correlation between these parameters, so that simultaneous higher coupling and {nu}-masses are allowed. Furthermore, models with a significant coupling and {nu}-mass are statistically favoured in respect to a cosmology with no coupling and negligible neutrino mass (our best fits are: C{approx}1/2 m{sub p}, m{sub {nu}{approx}0}.12 eV per flavor). We use a standard Monte Carlo Markov Chain approach, by assuming DE to be a scalar field self-interacting through Ratra-Peebles or SUGRA potentials.
  • Within the frame of cosmologies where Dark Energy (DE) is a self-interacting scalar field, we allow for a CDM-DE coupling and non-zero neutrino masses, simultaneously. In their 0-0 version, i.e. in the absence of coupling and neutrino mass, these cosmologies provide an excellent fit to WMAP, SNIa and deep galaxy sample spectra, at least as good as {Lambda}CDM. When the new degrees of freedom are open, we find that CDM-DE coupling and significant neutrino masses ({approx} 0.1 eV per {nu} species) are at least as likely as the 0-0 option and, in some cases, even statistically favoured.
