Abstract: The SuperCool inflation has the virtue of working "Naturally" at TeV scales and even much lower, which opens the possibility of using collider physics to probe inflation. In addition, the model introduces a new mechanism to end 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. Inflation ends, and the Universe rapidly reheats. The model also can generate the necessary perturbations for inflation and can satisfy constraints from Plank.
