Web6 de set. de 2024 · We study preheating following Higgs inflation in the Palatini formulation of gravity. 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).

Web6 de set. de 2024 · Our results provide further evidence that preheating in Palatini Higgs inflation happens within a single oscillation of the Higgs field about the bottom of its potential, consistent with the approximation of an instantaneous preheating.

WebWe consider the preheating in the Higgs inflation. We argue that the choice of the higher dimensional operator affects the dynamics of the preheating. 2. Talk Plan 1. Higgs inflaiton 2. Preheating and higher dim. op. 3. Standard Model The Higgs boson is only elementary scalar in the Standard Model. WebRecent analyses of cosmological data suggest the presence of an extra relativistic component beyond the Standard Model content. The Higgs-Dilaton cosmological model … WebIt has recently been suggested that at the post-inflationary stage of the mixed Higgs-R 2 model of inflation efficient particle production can arise from the tachyonic instability of the Higgs field. It might complete the preheating of the Universe if appropriate conditions are satisfied, especially in the Higgs-like regime. In this paper, we study this behavior in … simply yuh
