论文摘要
到目前为止，允许希格斯玻色子质量预测的多点临界（PMPC）的原理已应用于辐射产生的真空。如果此原理是基本的，则从目前目前未知的潜在物理学之后，PMPC必须适用于所有真空，包括以树级术语为主的多量表模型的多个真空吸尘器。我们首先激发了这个想法，然后通过将PMPC应用于Singlet标量暗物质模型的各种实现来体现它。我们从简并真空的需求中得出对暗物质属性的约束，并表明某些标量暗物质模型被PMPC排除，而在其他情况下，允许的参数空间受到约束。
The principle of multiple point criticality (PMPC), which allowed the prediction of the Higgs boson mass before its discovery, has so far been applied to radiatively generated vacua. If this principle is fundamental, following from some presently unknown underlying physics, the PMPC must apply to all vacua, including the multiple vacua of multi-scalar models dominated by tree-level terms. We first motivate this idea and then exemplify it by applying the PMPC to various realizations of singlet scalar dark matter models. We derive constraints on the dark matter properties from the requirement of degenerate vacua and show that some scalar dark matter models are ruled out by the PMPC, while in others the allowed parameters space is constrained.
