Overview

Analysis reveals reduced lithium-7 production in metal-poor halo stars, suggesting a need to revise nuclear models of Big Bang Nucleosynthesis.

Key Points

  • To resolve the discrepancy in lithium-7 abundance predicted by Big Bang nucleosynthesis compared to observations.
  • Utilized Global Complexity–Stability Theory (GCST) to analyze stability and production channels during Big Bang nucleosynthesis.
  • Assessed the temperature window of T ≈ 0.08–0.03 MeV and its effects on lithium production.
  • Investigated the stability index during non-equilibrium conditions.
  • Observed a lithium-7 overproduction of about 2.5–3.5 times higher than experimental values in metal-poor halo stars.
  • Identified suppression of 7Be production as the main cause of lithium deficit.
  • Demonstrated that declining stability relates to complexity growth in the early universe.
