论文摘要
我们进一步分析了参考文献中提出的双轴单肌通胀的现象学意义。物理。 Rev. D 104，L081302（2021），在重力波物理学中。我们表明，除了源自量规场不稳定性的手性重力波（GW）外，该模型还预测了大量的非手续的，标量的引力波，都在相同的频率左右达到峰值。我们发现，尽管手性GW密度具有更大的峰值，但非手力GWS可以以较慢的速度衰减时远离峰值。这提供了一个有趣的GW签名，可以通过Lisa和Decigo等未来的基于空间的干涉仪进行探测。
We further analyze phenomenological implications of double axion monodromy inflation proposed in Ref. Phys. Rev. D 104, L081302 (2021), in gravitational wave physics. We show that in addition to chiral gravitational waves (GW) originating from gauge field instability, the model also predicts significant amount of non-chiral, scalar-induced gravitational waves, both peaking at around the same frequencies. We find that although chiral GW density has much larger peak, non-chiral GWs can dominate away from the peak as they decay at a slower rate. This provides an interesting GW signature to be probed by future space-based interferometers such as LISA and DECIGO.
