The Tensor Desert

By L Alabidi

Abstract

We consider the question of whether it is worth building an experiment with the sole purpose of bringing the detectable limit on the tensor-to-scalar ratio down to 10^{-3}. We look at the inflationary models which give a prediction in this region and recap the current situation with the tensor mode, showing that there are only two known models inflation which give definitive predictions in the region 10^{-3}<r<10^{-2}
