The study suggests that the small-field inflation model can be tested through the production of gravitational waves from cosmic strings. Future experiments with gravitational wave detectors will determine or further constrain the parameter space in the model.
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.
