Can power spectrum observations rule out slow-roll inflation?

Article, Preprint English OPEN
Vieira, J. P. P.; Byrnes, Christian T.; Lewis, Antony;

The spectral index of scalar perturbations is an important observable that allows us to learn about inflationary physics. In particular, a detection of a significant deviation from a constant spectral index could enable us to rule out the simplest class of inflation mod... View more
