Big-Bang nucleosynthyesis: constraints on nuclear reaction rates, neutrino degeneracy, inhomogeneous and Brans-Dicke models
Riou Nakamura, Masa-aki Hasahimoto, Ryotaro Ichimasa +1
We review the recent progress in the Big-Bang nucleosynthesis which includes the standard and non-standard theory of cosmology, effects of neutrino degeneracy, and inhomogeneous nu…
Big-Bang Nucleosynthesis in comparison with observed helium and deuterium abundances - possibility of a non-standard model
R. Ichimasa, R. Nakamura, M. Hashimoto +1
Comparing the latest observed abundances of 4He and D, we make a ?2 analysis to see whether it is possible to reconcile primordial nucleosynthesis using up-to-date nuclear data of…
Brans-Dicke model constrained from Big Bang nucleosynthesis and magnitude redshift relations of Supernovae
E. P. B. A. Thushari, R. Nakamura, M. Hashimoto +1
The Brans-Dicke model with a variable cosmological term () has been investigated with use of the coupling constant of . Parameters inherent in this model are constrain…
