标题： Possible Relics from New Physics in the Early Universe: Inflation, the Cosmic Microwave Background, and Particle Dark Matter

摘要： 我回顾了粒子理论与早期宇宙学之间的两种不同联系：（1）宇宙微波背景（CMB）对暴胀的检验和（2）粒子暗物质。 通过即将到来的CMB温度图，可以精确测试暴胀所预测的平坦宇宙以及原初密度扰动接近标度不变的谱。 利用CMB偏振图可能探测到随机引力波背景。 我还讨论了CMB图的其他一些应用。 粒子理论已经提出了两个非常有动机的宇宙暗物质候选者：轴子和超对称粒子。 在这两种情况下，都有一系列实验正在开展以探测这些粒子。 我回顾了这些暗物质候选者的性质以及探测技术。 这里许多内容之前已出现在astro-ph/9712215和hep-ph/9710467中，但本文进行了更新并且大大扩展了内容。 显示英文摘要

摘要： I review two different connections between particle theory and early-Universe cosmology: (1) Cosmic-microwave-background (CMB) tests of inflation and (2) particle dark matter. The inflationary predictions of a flat Universe and a nearly scale-invariant spectrum of primordial density perturbations will be tested precisely with forthcoming maps of the CMB temperature. A stochastic gravitational-wave background may be probed with a map of the CMB polarization. I also discuss some other uses of CMB maps. Particle theory has produced two very well-motivated candidates for the dark matter in the Universe: an axion and a supersymmetric particle. In both cases, there are a variety of experiments afoot to detect these particles. I review the properties of these dark-matter candidates and these detection techniques. Much of the material here has appeared before in astro-ph/9712215 and hep-ph/9710467, but the article here is updated and also expanded considerably.
