A new bound on the neutrino mass from the SDSS baryon acoustic peak
نویسندگان
چکیده
We have studied bounds on the neutrino mass using new data from the Sloan Digital Sky Survey measurement of the baryon acoustic peak. We find that even in models with a running spectral index where the number of neutrinos and the dark energy equation of state are allowed to vary, the bound on the sum of neutrino masses is robustly below 0.5 eV. Using the SDSS Lyman-α constraint on the amplitude of the matter power spectrum at small scales pushes the bound to ∑ mν ≤ 0.30 eV (95% C.L.).

The neutrino mass bound from WMAP-3, the baryon acoustic peak, the SNLS supernovae and the Lyman-α forest
We have studied bounds on the neutrino mass using new data from the WMAP 3 year data, the Sloan Digital Sky Survey measurement of the baryon acoustic peak, the Type Ia supernovae from SNLS, and the Lyman-α forest. We find that even in the most general models with a running spectral index where the number of neutrinos and the dark energy equation of state are allowed to vary, the 95% C.L. bound ...
متن کاملConfrontation of MOND Predictions with WMAP First Year Data
I present a model devoid of non-baryonic cold dark matter (CDM) which provides an acceptable fit to the WMAP data for the power spectrum of temperature fluctuations in the cosmic background radiation (CBR). An a priori prediction of such no-CDM models was a first-to-second peak amplitude ratio A1:2 ≈ 2.4. WMAP measures A1:2 = 2.34 ± 0.09. The baryon content is the dominant factor in fixing this...
متن کاملNeutrinoless double beta decay with scalar bilinears
One possible probe to physics beyond the standard model is to look for scalar bilinears, which couple to two fermions of the standard model. We point out that the scalar bilinears allow new diagrams contributing to the neutrinoless double beta decay. The upper bound on the neutrinoless double beta decay lifetime would then give new constraints on the ratio of the masses of these scalars to thei...
متن کاملDecaying neutrino and a high cosmological baryon density
The low second acoustic peak in the recent Boomerang data may indicate a cosmological baryon density which is larger than allowed by standard big bang nucleosynthesis. We show that the decay of the tau-neutrino: ντ → νe +φ, where νe is the electron neutrino and φ is a scalar, essentially can assure agreement between BBN calculations and light element observations for a large baryon density.
متن کاملPredictions of the most minimal see-saw model
We derive the most minimal see-saw texture from an extra-dimensional dynamics. If LMA is the solution to the solar neutrino problem, it predicts θ13 = 0.07± 0.02 and mee = 2.5± 0.7 meV. Assuming thermal leptogenesis, the sign of the CP-phase measurable in neutrino oscillations, together with the sign of baryon asymmetry, determines the order of heavy neutrino masses. Unless heavy neutrinos are ...
