Description
We consider a classically scale invariant model of scalar field inflation. The treel level potential contains only quartic terms and the scale of inflation is generated dynamically. Both hilltop and chaotic inflation are possible. The model can explain the BICEP2 signal of tensor modes. Reheating takes place via decay into right handed neutrinos.
