We point out that the preheating proceeds much more violently than previously thought. Web2.2. Higgs Inflation From Approximate Scale Invariance. Although the toy model presented above contains many of the key ingredients of Higgs inflation, it is not phenomenologically viable. In particular, the Einstein-frame potential is completely shift-symmetric and does not allow for inflation to end. floral print bow ties
