论文摘要
我们重新审视了暗物质由稳定的鳞片粘合球组成的可能性，该稳定的黑暗胶合球（\ rm su}（3）$量规理论仅与重力结合。第一次在热有效理论中研究了深色粘合球的遗物丰度，该理论涉及强耦合动力学。我们分析的重要组成部分是使用晶格模拟拟合的有效潜力。我们预测，遗物的丰度在$0.12ζ_{t}^{ - 3}λ/（137.9 {\ rm ev}）\ LisesimωH^{2} \ lyseSim0.12ζ_ $ζ_{t} $可见的扇形扇区温度比和不确定性来自拟合与晶格数据。该预测比现有的胶球丰度小的数量级导致文献产生。我们的框架可以很容易地推广到不同的量规组，并修改了宇宙学历史，为一致探索强耦合的黑暗部门及其宇宙学含义铺平了道路。
We revisit the possibility that Dark Matter is composed of stable scalar glueballs of a confining dark ${\rm SU}(3)$ gauge theory coupled only to gravity. The relic abundance of dark glueballs is studied for the first time in a thermal effective theory accounting for strong-coupling dynamics. An important ingredient of our analysis is the use of an effective potential for glueballs that is fitted by lattice simulations. We predict the relic abundance to be in the range $0.12ζ_{T}^{-3}Λ/(137.9 {\rm eV}) \lesssim Ωh^{2}\lesssim 0.12ζ_{T}^{-3}Λ/(82.7 {\rm eV})$, with $Λ$ being the confinement scale, $ζ_{T}$ the visible-to-dark sector temperature ratio and the uncertainty is coming from the fit to lattice data. This prediction is an order of magnitude smaller than the existing glueball abundance results in the literature. Our framework can be easily generalised to different gauge groups and modified cosmological histories paving the way towards consistent exploration of strongly-coupled dark sectors and their cosmological implications.
