论文摘要
我们表明，超轻标量的非扰动衰减到阿贝尔仪表玻色子中，最近被认为是对哈勃张力的可能解决方案，它会产生重力波的随机背景，该背景受宇宙微波背景约束。我们模拟了共鸣暗光子产生和相关的引力波的产生的完整非线性动力学，发现信号超过了我们考虑的整个参数空间的约束。我们的发现表明，从早期黑暗能量衰减中产生重力波可能会提供这些模型的独特探测。
We show that the nonperturbative decay of ultralight scalars into Abelian gauge bosons, recently proposed as a possible solution to the Hubble tension, produces a stochastic background of gravitational waves which is constrained by the cosmic microwave background. We simulate the full nonlinear dynamics of resonant dark photon production and the associated gravitational wave production, finding the signals to exceed constraints for the entire parameter space we consider. Our findings suggest that gravitational wave production from the decay of early dark energy may provide a unique probe of these models.
