Determination of Omega_b From Big Bang Nucleosynthesis in the Presence of Regions of Antimatter
Elina Sihvola
Production of regions of antimatter in the early universe is predicted in many baryogenesis models. Small scale antimatter regions would annihilate during or soon after nucleosynth…
Inhomogeneous Big Bang Nucleosynthesis and the High Baryon Density Suggested by Boomerang and MAXIMA
Hannu Kurki-Suonio, Elina Sihvola
The recent Boomerang and MAXIMA data on the cosmic microwave background suggest a large value for the baryonic matter density of the universe, omega_b = 0.03. This density is large…
Antimatter Regions in the Early Universe and Big Bang Nucleosynthesis
Hannu Kurki-Suonio, Elina Sihvola
We have studied big bang nucleosynthesis in the presence of regions of antimatter. Depending on the distance scale of the antimatter region, and thus the epoch of their annihilatio…
Constraining Antimatter Domains in the Early Universe with Big Bang Nucleosynthesis
Hannu Kurki-Suonio, Elina Sihvola
We consider the effect of a small-scale matter-antimatter domain structure on big bang nucleosynthesis and place upper limits on the amount of antimatter in the early universe. For…
Inhomogeneous Big-Bang Nucleosynthesis in Light of Recent Observations
K. Kainulainen, H. Kurki-Suonio, E. Sihvola
We consider inhomogeneous big bang nucleosynthesis in light of the present observational situation. Different observations of He-4 and D disagree with each other, and depending on…
