We study dressed inflation with a cuscuton and find a novel exact power-law solution. It is well known that the conventional power-law inflation is inconsistent with the Planck data. In contrast to this standard lore, we find that power-law inflation with a cuscuton can be reconciled with the Planck data. Moreover, we argue that the cuscuton generally ameliorates inflation models so that predictions are consistent with observations.

Cuscuton-like contribution to dark energy evolution
A cuscuton-like kinetic term is combined with quintessence fields in a first-order formalism, producing analytical dark-energy histories, but the advertised phantom phases rely on an inconsistent sign choice and the A...
