C.A. Bertulani, Shubhchintak, and A.M. Mukhamedzhanov
TL;DR
This paper reviews the cosmological lithium problems and explores recent theoretical and experimental approaches, including electron screening, dark matter universes, non-extensive statistics, and nuclear physics solutions, to address discrepancies in lithium abundance predictions.
Contribution
It introduces novel theoretical considerations like dark matter parallel universes and non-extensive statistics, and summarizes recent experimental measurements relevant to lithium problems.
Findings
Electron screening effects are significant in lithium synthesis.
Dark matter parallel universes could influence nucleosynthesis.
Recent cross-section measurements provide new insights into lithium production.
Abstract
We briefly describe the cosmological lithium problems followed by a summary of our recent theoretical work on the magnitude of the effects of electron screening, the possible existence of dark matter parallel universes and the use of non-extensive (Tsallis) statistics during big bang nucleosynthesis. Solutions within nuclear physics are also discussed and recent measurements of cross-sections based on indirect experimental techniques are summarized.
