  The Big Bang Nucleosynthesis (BBN) model is a cornerstone for the
understanding of the evolution of the early universe, making seminal
predictions that are in outstanding agreement with the present observation of
light element abundances in the universe. Perhaps, the only remaining issue to
be solved by theory is the so-called "lithium abundance problem". Dedicated
experimental efforts to measure the relevant nuclear cross sections used as
input of the model have lead to an increased level of accuracy in the
prediction of the light element primordial abundances. The rise of indirect
experimental techniques during the preceding few decades has permitted the
access of reaction information beyond the limitations of direct measurements.
New theoretical developments have also opened a fertile ground for tests of
physics beyond the standard model of atomic, nuclear, statistics, and particle
physics. We review the latest contributions of our group for possible solutions
of the lithium problem.
