Description
SuperCool Inflation is a new technically natural model
which gives a graceful exit to old inflation. The Universe
starts off hot and trapped in a false vacuum. The Universe
supercools and inflates solving the horizon and flatness
problems. The inflaton couples to a set of QCD like
fermions. When the fermions' non-Abelian gauge group
freezes, the Yukawa terms generate a tadpole for the
inflaton, which removes the barrier. The model works at
scales which can be probed by LHC. Finally, we introduce a
light spectator field to generate density perturbations,
which match the CMB.
