杨-米尔斯凝聚体中的暗能量和暗物质与Peccei-Quinn机制
Dark Energy and Dark Matter from Yang-Mills Condensate and the Peccei-Quinn mechanism
摘要：
我们分析了冷轴子暗物质与暗胶子凝聚弱耦合的模型，再现了暗能量。我们首先回顾了如何使用泛函重整化群方法来恢复暗能量的行为，并将我们的研究建立在非微扰确定的有效拉格朗日量的性质上。然后，在$G_{SM}\times SU(2)_{D}\times U(1)_{PQ}$的背景下，我们考虑YMC与QCD轴子的相互作用。我们预测，在宇宙学时间内，暗能量密度将转移到暗物质密度，这可以在下一代致力于暗能量测量的实验中进行测试。
英文摘要：
We analyze a model of cold axion Dark Matter weakly coupled with a dark gluon condensate, reproducing Dark Energy. We first review how to recover the Dark Energy behavior using the functional renormalization group approach, and ground our study on the properties of the effective Lagrangian, to be determined non-perturbatively. Then, within the context of $G_{SM}\times SU(2)_{D}\times U(1)_{PQ}$, we consider YMC interactions with QCD axions. We predict a transfer of Dark Energy density into Dark Matter density in a cosmological time that can be tested in the next generation of experiments dedicated to Dark Energy measures.
