Description
I will discuss the out-of-equilibrium dynamics of the Standard Model after inflation, when the Higgs is weakly coupled to the inflationary sector. During inflation the Higgs forms a condensate, which oscillates short after inflation ends, transferring most of its energy to the SU(2)xU(1) gauge fields via parametric resonance. I have studied this process with classical lattice simulations, including explicitly the non-Abelian Higgs-gauge interactions in the lattice. I will describe and quantify the main time scales, energy ratios, and field spectra, and compare our results with an equivalent Abelian-Higgs modelling.
