Large Non-Gaussianities in Single Field Inflation

  title={Large Non-Gaussianities in Single Field Inflation},
  author={Xingang Chen and Richard Easther and Eugene A. Lim},
We compute the 3-point correlation function for a general model of inflation driven by a single, minimally coupled scalar field. Our approach is based on the numerical evaluation of both the perturbation equations and the integrals which contribute to the 3-point function. Consequently, we can analyze models where the potential has a “feature”, in the vicinity of which the slow roll parameters may take on large, transient values. This introduces both scale and shape dependent non-Gaussianities… CONTINUE READING
