论文摘要
经典规模的不变性（CSI）可能会阐明弱尺度的起源，但是对标准模型的现实CSI扩展需要一个玻感触发器。我们提出了标量暗物质（DM）字段$ x $作为触发因素，在成功的辐射破裂和DM现象学之间建立了牢固的联系。后者将断裂量表迫使$ \ sim {\ cal o}（\ rm tev）$。它通过重力波（CSI相变（CSIPT）的尖锐预测）来亮起这种情况的测试前景，该预测是一阶并且具有强冷冷的强烈预测。此外，我们仔细处理一些通常用于分析CSIPT但可能会错过的技术。特别是，我们阐明了在单场情况下使用的Witten公式的不精确，以计算气泡成核速率和压力，即Witten近似的本质是高温膨胀的有效性。
Classical scale invariance (CSI) may shed light on the weak scale origin, but the realistic CSI extension to the standard model requires a bosonic trigger. We propose a scalar Dark Matter(DM) field $X$ as the trigger, establishing a strong connection between the successful radiative breaking of CSI and DM phenomenologies. The latter forces the breaking scale to $\sim {\cal O}(\rm TeV)$. It brightens the test prospect of this scenario via gravitational wave, a sharp prediction of CSI phase transition (CSIPT), which is first order and has strong supercooling. Moreover, we carefully deal with some techniques which are commonly used to analyze CSIPT but maybe missed. In particular, we clarify the imprecision of Witten's formula used in the single field case to calculate the bubble nucleation rate and stress that the essence of Witten's approximation is the validity of high temperature expansion.
