Future CMB and galaxy surveys are forecast to constrain the alpha-attractor quintessential inflation parameter to alpha = 2 ± 0.17 and the spectral index to n_s = 0.965 ± 0.0014.

abstract
We investigate two classes of models of quintessential inflation, based upon canonical as well as noncanonical scalar fields. In particular, introducing potentials steeper than the standard exponential, we construct models that can give rise to a successful inflationary phase, with signatures consistent with Planck 2015 results. Additionally, using nonminimal coupling of the scalar field with massive neutrino matter, we obtain the standard thermal history of the Universe, with late-time cosmic acceleration as the last stage of evolution. In both cases, inflation and late-time acceleration are connected by a tracker solution.

Forecasting constraints on quintessential inflation from future generation of galaxy and CMB surveys
Future CMB and galaxy surveys are forecast to constrain the alpha-attractor quintessential inflation parameter to alpha = 2 ± 0.17 and the spectral index to n_s = 0.965 ± 0.0014.
