Abstract

Test of non-Gaussianity can be useful to reveal the origin of primordial perturbations. We can obtain information about number of fields contributing to the curvature perturbation by using fnl and taunl. Detection of all the non-linearity parameters greatly helps us constrain the model of the early Universe. Very soon, Planck results will tell us something.
