大爆炸核合成与宇宙背景中微子

Big bang nucleosynthesis and the cosmic neutrino background

  • 摘要: 文章基于大爆炸宇宙学描述了发生于宇宙早期的中微子退耦与轻核素合成事件。退耦后的中微子形成宇宙的背景之一。文章介绍了几种探测宇宙背景中微子的方法,侧重于利用β衰变核俘获超低动能的中微子。

     

    Abstract: We present a brief overview of the neutrino decoupling and big bang nucleosynthesis in the early universe. The big bang relic neutrinos formed one of the backgrounds of the universe.A few possible ways to directly detect the cosmic neutrino background are briefly introduced, and particular attention is paid to the relic neutrino capture on β-decaying nuclei.
