Implications of the scalar tilt for the tensor-to-scalar ratio

We investigate the possible implications of the measured value of the scalar tilt ns for the tensor-to-scalar ratio r in slow-roll, single-field inflationary models. The measured value of the tilt satisfies ns-1∼1/N∗, where N∗∼60 is the number of e-folds for observationally relevant scales. If this...
