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.
