论文摘要
我提出了对隐形暗物质有限温度动力学的晶格调查的首次结果，这增加了标准模型A新的SU（4）量规部门，具有四个中等重的基本费用。晶格强大的动态协作的这项工作是基于过去直接检测的研究，并通过分析早期的宇宙SU（4）限制过渡来对隐形暗物质进行搜索，如果它是第一阶，它会产生重力波的随机背景。除了描述观察到一阶转变的参数空间外，我还讨论了我们正在分析的数量，以预测所得的重力波谱。
I present first results from ongoing lattice investigations into the finite-temperature dynamics of stealth dark matter, which adds to the standard model a new SU(4) gauge sector with four moderately heavy fundamental fermions. This work by the Lattice Strong Dynamics Collaboration builds on past studies of direct detection and collider searches for stealth dark matter, by analyzing the early-universe SU(4) confinement transition, which produces a stochastic background of gravitational waves if it is first order. In addition to delineating the parameter space in which a first-order transition is observed, I discuss the quantities we are analyzing in order to predict the resulting gravitational-wave spectrum.
