Improving the Single Scalar Consistency Relation
  We propose a test of single-scalar inflation based on using the well-measured
scalar power spectrum to reconstruct the tensor power spectrum, up to a single
integration constant. Our test is a sort of integrated version of the
single-scalar consistency relation. This sort of test can be used effectively,
even when the tensor power spectrum is measured too poorly to resolve the
tensor spectral index. We give an example using simulated data based on a
hypothetical detection with tensor-to-scalar ratio $r = 0.01$. Our test can
also be employed for correlating scalar and tensor features in the far future
when the data is good.
