摘要：
在大质量标量-张量引力中，核心坍缩超新星是标量极化引力波的强源，这些信号可以在很远的距离上被探测到。由于波在大质量标量场中传播具有色散性质，引力波信号持续时间很长，许多此类信号可以相互重叠形成随机背景。利用近邻宇宙中超新星事件种群的不同模型，我们针对能够促进强标量化的理论参数，计算了大质量标量-张量引力中核心坍缩事件产生的标量极化随机引力波背景的能量密度预测。所得能量密度低于当前对高斯随机引力波背景的限制，但足够大，可以在当前一代探测器达到设计灵敏度时被探测到，这表明不久将有可能对大质量标量-张量引力的参数空间施加新的约束。
英文摘要：
In massive scalar-tensor gravity, core-collapse supernovae are strong sources of scalar-polarized gravitational waves. These can be detectable out to large distance. The dispersive nature of the propagation of waves in the massive scalar field mean the gravitational wave signals are long lived and many such signals can overlap to form a stochastic background. Using different models for the population of supernova events in the nearby universe, we compute predictions for the energy-density in the stochastic scalar-polarized gravitational wave background from core-collapse events in massive scalar-tensor gravity for theory parameters that facilitate strong scalarization. The resulting energy density is below the current constraints on a Gaussian stochastic gravitational wave background but large enough to be detectable with the current generation of detectors when they reach design sensitivity, indicating that it will soon be possible to place new constraints on the parameter space of massive scalar-tensor gravity.
