Non-Gaussianities from the Standard Model Higgs

De Simone, Andrea
Published in Journal of Cosmology and Astroparticle Physics. 2013, vol. 2013, no. 01, p. 037-037
Abstract We have recently proposed that the Standard Model Higgs might be responsible for generating the cosmological perturbations of the universe by acting as an isocurvature mode during a de Sitter inflationary stage. In this paper we study the level of non-Gaussianity in the cosmological perturbations which are inevitably generated due to the non-linearities of the Standard Model Higgs potential. In particular, for the current central value of the top mass, we find that a future detection of non-Gaussianity would exclude the detection of tensor modes by the PLANCK satellite.
