摘要

Following a recent suggestion of axion cooling of photons between the nucleosynthesis and recombination epochs in the Early Universe, we investigate a hybrid model with both axions and relic supersymmetric particles. In this model we demonstrate that the ⁷Li abundance can be consistent with observations without destroying the important concordance of deuterium abundance.
