The Cosmological Lithium Problem Revisited
  After a brief review of the cosmological lithium problem, we report a few
recent attempts to find theoretical solutions by our group at Texas A&M
University (Commerce & College Station). We will discuss our studies on the
theoretical description of electron screening, the possible existence of
parallel universes of dark matter, and the use of non-extensive statistics
during the Big Bang nucleosynthesis epoch. Last but not least, we discuss
possible solutions within nuclear physics realm. The impact of recent
measurements of relevant nuclear reaction cross sections for the Big Bang
nucleosynthesis based on indirect methods is also assessed. Although our
attempts may not able to explain the observed discrepancies between theory and
observations, they suggest theoretical developments that can be useful also for
stellar nucleosynthesis.
