我们考虑引力声波信号产生的一阶相变的理论与通用重整化的热有效势的幂律形式。我们发现引力波信号的频率和振幅可以直接与热有效势的参数相关。这导致了一个普遍的结论：如果暗希格斯粒子的质量小于暗希格斯真空期望值的1%，那么引力波信号将在所有即将到来的和计划中的引力波观测站都无法观测到。虽然对宇宙相变时引力波产生的理解仍在发展中，但我们预计这一结果将是可靠的。
We consider gravitational sound wave signals produced by a first-order phase transition in a theory with a generic renormalizable thermal effective potential of power law form. We find the frequency and amplitude of the gravitational wave signal can be related in a straightforward manner to the parameters of the thermal effective potential. This leads to a general conclusion; if the mass of the dark Higgs is less than 1% of the dark Higgs vacuum expectation value, then the gravitational wave signal will be unobservable at all upcoming and planned gravitational wave observatories. Although the understanding of gravitational wave production at cosmological phase transitions is still evolving, we expect this result to be robust.
