论文摘要
我们探索了一类简单的超级重力模型的重力波(GW)现象学,这些模型可以解释和统一通货膨胀和原始黑洞(PBH)作为暗物质(DM)。我们(修改的)超级强制模型自然会导致两场吸引子型双重通胀,其第一阶段是由Starobinsky Scalaron驱动的,第二阶段由另一个属于超级重度多重的标量驱动。我们的超级重力模型中的PBHS形成是有效的,与所有观察性约束兼容,并预测了随机GW背景。我们计算PBH诱导的GW功率谱,并表明可以在未来的基于空间的GW干涉仪的灵敏度曲线中检测到GW信号,例如Lisa,Decigo,Decigo,Taiji和Tianqin项目,从而显示出GW Physicts中超级精神的预测能力及其兼容性。
We explore the Gravitational Waves (GW) phenomenology of a simple class of supergravity models that can explain and unify inflation and Primordial Black Holes (PBH) as Dark Matter (DM). Our (modified) supergravity models naturally lead to a two-field attractor-type double inflation, whose first stage is driven by Starobinsky scalaron and the second stage is driven by another scalar belonging to a supergravity multiplet. The PBHs formation in our supergravity models is efficient, compatible with all observational constraints, and predicts a stochastic GW background. We compute the PBH-induced GW power spectrum and show that GW signals can be detected within the sensitivity curves of the future space-based GW interferometers such as LISA, DECIGO, TAIJI and TianQin projects, thus showing predictive power of supergravity in GW physics and their compatibility.
