论文摘要
对隐藏部门的塔相互耦合，并进行了这些隐藏扇区之一，并进行了这些隐藏扇区的分析，并研究了此类耦合对可见扇区物理学的含义。因此，分析考虑了$ n $的隐藏扇区数量，其中可见扇区仅与隐藏的扇区1伴侣，而后一对夫妇也与隐藏的扇区2，而隐藏的扇区2夫妇则与隐藏的扇区3等。在这种设置中生成了一组隐藏部门与可见扇区的无效耦合。通常，这些部门中的每个部门都生活在不同的热水浴中。我们开发了一个封闭形式的耦合玻尔兹曼方程，以与每个热浴的温度和数量密度相关。然后，我们将形式主义应用于不同部门之间具有标量门户的简化模型。与暗物质直接检测实验有关的预测和深色辐射的未来CMB探针。
An analysis of a tower of hidden sectors coupled to each other, with one of these hidden sectors coupled to the visible sector, is given and the implications of such couplings on physics in the visible sector are investigated. Thus the analysis considers $n$ number of hidden sectors where the visible sector couples only to hidden sector 1, while the latter couples also to hidden sector 2, and the hidden sector 2 couples to hidden sector 3 and so on. A set of successively feeble couplings of the hidden sectors to the visible sector are generated in such a set up. In general each of these sectors live in a different heat bath. We develop a closed form set of coupled Boltzmann equations for the correlated evolution of the temperatures and number densities of each of the heat baths. We then apply the formalism to a simplified model with scalar portals between the different sectors. Predictions related to dark matter direct detection experiments and future CMB probes of dark radiation are made.
