论文摘要
宇宙字符串和一阶相变是随机重力波背景（SGWB）的两个主要来源。在这项工作中，我们研究了从一阶相变之后形成的宇宙弦的随机重力波辐射。对于一阶相变的，在远远超出电动量尺度的温度下，将无法通过未来的重力波干涉仪达到重力波信号。 The gravitational waves from cosmic strings that formed after the phase transition can be detected by future gravitational wave detectors in a wide range of frequency, and therefore its imprints can serve to search for firs-order phase transitions at high scales with the phase transition temperature: $ \mathcal{O}(10^8)$ GeV $ \leq T_n$ $\leq \ Mathcal {O}（10^{11}）$ GEV。
Cosmic strings and first-order phase transition are two main sources for the stochastic gravitational wave background (SGWB). In this work, we study the stochastic gravitational wave radiation from cosmic string which is formed after the first-order phase transition. For the first-order phase transition occurs at temperature far beyond the electroweak scale, the gravitational wave signal cannot be reached by the future gravitational wave interferometers. The gravitational waves from cosmic strings that formed after the phase transition can be detected by future gravitational wave detectors in a wide range of frequency, and therefore its imprints can serve to search for firs-order phase transitions at high scales with the phase transition temperature: $ \mathcal{O}(10^8)$ GeV $ \leq T_n$ $\leq \mathcal{O}(10^{11})$ GeV.
