We numerically evolve perturbations of the radial mode of the Higgs field … Web4 de out. de 2013 · The preheating in the model was analysed in [37, 38]. After the end of inflation, χ < M P (), the potential can be approximated by a quadratic function (with just a small quartic part around the origin corresponding to the SM potential for χ < M P /ξ).
