摘要：

大多数普通物质的质量都来自量子色动力学（QCD）。一个类似的强动力学，暗QCD，可以用来解释暗物质的质量起源。利用两个规范耦合的红外固定点，我们提供了一个动力学机制，将暗QCD禁闭尺度与我们的QCD尺度联系起来，从而为可比较的暗重子和质子质量提供了一个解释。再加上早期宇宙中产生等量的暗重子和普通重子不对称的机制，暗物质和普通物质能量密度的相似性就可以自然地得到解释。对于一个大类的规范群表示，粒子下的QCD和暗QCD，必要的成分产生的红外固定点充电，被发现有质量在1至2 TeV，这套规模的暗物质直接检测和新的对撞机签名涉及可见光和暗喷流。

英文摘要：

Most of the mass of ordinary matter has its origin from quantum chromodynamics (QCD). A similar strong dynamics, dark QCD, could exist to explain the mass origin of dark matter. Using infrared fixed points of the two gauge couplings, we provide a dynamical mechanism that relates the dark QCD confinement scale to our QCD scale, and hence provides an explanation for comparable dark baryon and proton masses. Together with a mechanism that generates equal amounts of dark baryon and ordinary baryon asymmetries in the early universe, the similarity of dark matter and ordinary matter energy densities can be naturally explained. For a large class of gauge group representations, the particles charged under both QCD and dark QCD, necessary ingredients for generating the infrared fixed points, are found to have masses at one to two TeV, which sets the scale for dark matter direct detection and novel collider signatures involving visible and dark jets.
