I will discuss the role of a Higgs particle with mass of about 126 GeV in early universe cosmology.
In particular, it can be responsible for the generation of the cosmological perturbations, giving rise to the anisotropies in the Cosmic Microwave Background and in Large-Scale Structure formation. I will also discuss the level of Non-Gaussianities due to the non-linearities of the Higgs potential, and the correlations among particle physics and cosmological measurements.
