Power series inflation and primordial gravitational waves
The tensor-to-scalar ratio can be measured by observing the polarization of photos in the cosmic microwave background.It shows very strong power on constraining inflation models.However,for a single field inflation model,it can not predict both a large tensor-to-scalar ratio and a large running of t...
