标题： Alternative Solutions to Big Bang Nucleosynthesis

摘要： 大爆炸核合成（SBBN）已经取得了显著的成功，它可能是对所发生事件的正确且充分的描述。然而，对标准图像变化的兴趣来自两个方面：首先，大爆炸核合成可用于限制早期宇宙的物理规律；其次，SBBN的预测与观测丰度之间可能存在一些差异。SBBN的各种替代方案包括非均匀核合成、反物质核合成和非标准中微子物理。 显示英文摘要

摘要： Standard big bang nucleosynthesis (SBBN) has been remarkably successful, and it may well be the correct and sufficient account of what happened. However, interest in variations from the standard picture come from two sources: First, big bang nucleosynthesis can be used to constrain physics of the early universe. Second, there may be some discrepancy between predictions of SBBN and observations of abundances. Various alternatives to SBBN include inhomogeneous nucleosynthesis, nucleosynthesis with antimatter, and nonstandard neutrino physics.
