Non-BBN Constraints On The Key Cosmological Parameters
G. Steigman, N. Hata, J. E. Felten
Since the baryon-to-photon ratio "eta" is in some doubt at present, we ignore the constraints on eta from big bang nucleosynthesis (BBN) and fit the three key cosmological paramete…
Non-Nucleosynthetic Constraints on the Baryon Density and Other Cosmological Parameters
G. Steigman, N. Hata, J. E. Felten
Because the baryon-to-photon ratio eta_{10} is in some doubt, we drop nucleosynthetic constraints on eta_{10} and fit the three cosmological parameters (h, Omega_M, eta_{10}) to fo…
Metal Abundance in the Solar Interior
M. Fukugita, N. Hata
It is shown that the metal abundance in the solar interior is constrained from the current solar neutrino experiment, even if one allows neutrino conversion in the sun due to neutr…
Solutions to Solar Neutrino Anomaly
Naoya Hata, Paul Langacker
We present an updated analysis of astrophysical solutions, two-flavor MSW solutions, and vacuum oscillation solutions to the solar neutrino anomaly. The recent results of each of t…
Cosmological Implications of Two Conflicting Deuterium Abundances
N. Hata, G. Steigman, S. Bludman +1
Constraints on big bang nucleosynthesis (BBN) and on cosmological parameters from conflicting deuterium observations in different high red-shift QSO systems are discussed. The high…
Big Bang Nucleosynthesis in Crisis?
N. Hata, R. J. Scherrer, G. Steigman +4
A new evaluation of the constraint on the number of light neutrino species (N_nu) from big bang nucleosynthesis suggests a discrepancy between the predicted light element abundance…
