混合轴子暗物质模型中大爆炸核合成的解

Solution to Big-Bang Nucleosynthesis in Hybrid Axion Dark Matter Model

Motohiko Kusakabe, A. B. Balantekin, Toshitaka Kajino, Y. Pehlivan

摘要:

继最近的建议,轴子冷却的光子之间的核合成和重组时代在早期宇宙,我们研究了一个混合模型与轴子和遗物超对称粒子。在这个模型中,我们证明了7Li丰度可以与观测一致,而不会破坏氘丰度的重要一致性。

英文摘要:

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.
