论文摘要
我们描述了扰动单位性约束的计算的自动化，包括具有颜色电荷的标量及其在Sarah 4.14.4中的释放。我们将其与真空稳定性约束一起应用于具有五颜六色的介体和有趣衰减的简单暗物质模型，并显示它如何导致绑定在热遗物深色物质上，远低于经典的griest-kamionkowski限制。
We describe the automation of the calculation of perturbative unitarity constraints including scalars that have colour charges, and its release in SARAH 4.14.4. We apply this, along with vacuum stability constraints, to a simple dark matter model with colourful mediators and interesting decays, and show how it leads to a bound on a thermal relic dark matter mass well below the classic Griest-Kamionkowski limit.
