摘要

我们考虑了轴子/类轴子粒子切尔-西蒙斯引力耦合的情况，这样引力波就可以在暴胀后的早期宇宙中由轴子波参量共振直接产生。与经过深入研究的轴子光子耦合相比，这种轴子引力项的约束较小，可以为引力波提供一个直接而有效的产生渠道。这种随机引力波可以通过天基/地基引力波探测器或脉冲星定时阵列在广泛的轴心质量和衰变常数范围内探测到。

Gravitational waves from axion wave production

We consider a scenario with axions/axion-like particles Chern–Simons gravity coupling, such that gravitational waves can be produced directly from axion wave parametric resonance in the early universe after inflation. This axion gravity term is less constrained compared to the well-searched axion photon coupling and can provide a direct and efficient production channel for gravitational waves. Such stochastic gravitational waves can be detected by either space/ground-based gravitational wave detectors or pulsar timing arrays for a broad range of axion masses and decay constants.
