摘要
The detection of a large local form of non-Gaussianity is considered to be able to rule out all single field inflation models. This statement is based on the single field consistency condition. Despite the awareness of some implicit assumptions in the derivation of this condition and the demonstration of corresponding examples that illustrate these caveats, to date there is still no explicit and self-consistent model which can serve as a counterexample to this statement. We present such a model in this letter.
