The scale of small-field inflation cannot be constrained via primordial gravitational waves through measurement of tensor-to-scalar ratio r. In this study, I show that if cosmic strings are produced after symmetry breaking at the end of hilltop supernatural inflation, this small-field inflation model can be tested through the production of gravitational waves from cosmic strings. Future experiments of gravitational wave detectors will determine or further constrain the parameter space in the model.

用引力波测试山顶超自然膨胀

小场暴胀的规模不能通过原始引力波通过测量张量与标量比 r 来限制。在这项研究中，我展示了如果宇宙弦是在山顶超自然暴胀结束时对称破缺后产生的，那么这种小场暴胀模型可以通过宇宙弦产生引力波来测试。未来引力波探测器的实验将确定或进一步约束模型中的参数空间。
