# Generic inference of inflation models by non-Gaussianity and primordial power spectrum reconstruction

@article{Dorn2014GenericIO, title={Generic inference of inflation models by non-Gaussianity and primordial power spectrum reconstruction}, author={Sebastian Dorn and Erandy Ramirez and Kerstin E. Kunze and Stefan Hofmann and Torsten A. Ensslin}, journal={Journal of Cosmology and Astroparticle Physics}, year={2014}, volume={2014}, pages={048 - 048} }

We present a generic inference method for inflation models from observational data by the usage of higher-order statistics of the curvature perturbation on uniform density hypersurfaces. This method is based on the calculation of the posterior for the primordial non-Gaussianity parameters fNL and gNL, which in general depend on specific parameters of inflation and reheating models, and enables to discriminate among the still viable inflation models. To keep analyticity as far as possible to…
