Possible explanation of primordial 7Li deficit

Abstract A reduction mechanism of the theoretically predicted excessive abundance of 7Li via baryons evaporated by primordial black holes is suggested. It is shown that the fraction of 7Li with respect to the number density of baryons can be diminished down to the observed value via the process of 7...
