摘要:

我们进一步分析了在物理评论D 104,L081302(2021)中提出的双轴子单值暴胀在引力波物理中的唯象意义。我们发现,除了手征引力波(GW)起源于规范场的不稳定性,该模型还预测了显着数量的非手征,标量诱导的引力波,都在相同的频率附近达到峰值。我们发现,虽然手性GW密度有更大的峰值,非手性GW可以占主导地位的峰值,因为他们在一个较慢的速度衰减。这提供了一个有趣的GW签名,由未来的天基干涉仪,如LISA和DECIGO探测。

英文摘要:

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.
