作者：格雷欣，MI; Lou，HK; ZureK，KM|摘要：© 2018作者。我们计算了在早期宇宙中合成的非对称暗物质-金块-的束缚态的质量函数。我们应用我们的结果从核模型计算的块金密度和结合能，以获得典型的块金大小退出合成的分析估计。我们数值求解玻尔兹曼方程的合成，包括两到两个融合反应，估计瓶颈的质量函数退出合成的影响。这些结果为将来的姊妹论文中研究宇宙晚期的金块宇宙学提供了基础。
Author(s): Gresham, MI; Lou, HK; ZureK, KM | Abstract: © 2018 authors. We compute the mass function of bound states of asymmetric dark matter - nuggets - synthesized in the early Universe. We apply our results for the nugget density and binding energy computed from a nuclear model to obtain analytic estimates of the typical nugget size exiting synthesis. We numerically solve the Boltzmann equation for synthesis including two-to-two fusion reactions, estimating the impact of bottlenecks on the mass function exiting synthesis. These results provide the basis for studying the late Universe cosmology of nuggets in a future companion paper.
