宇宙弦的引力波与一级相变

Gravitational waves from cosmic strings and first-order phase transition

Ruiyu Zhou, Ligong Bian

摘要:

宇宙弦和一阶相变是随机引力波背景的两个主要来源。本文研究了一级相变后宇宙弦的随机引力波辐射。由于一级相变发生在远超电弱标度的温度下,未来的引力波干涉仪无法探测到引力波信号。在相变后形成的宇宙弦的引力波可以被未来的引力波探测器在很宽的频率范围内探测到,因此它的印记可以用来搜索具有相变温度的高尺度的一级相变:$ \mathcal{O}(10^8)$ GeV $ \leq T_n$ $\leq \mathcal{O}(10^{11})$ GeV。

英文摘要:

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.
