Web12 de abr. de 2024 · We study the details of preheating in Palatini Higgs inflation. We show, that contrary to what happens in the metric formulation of the model, the Universe does not reheat through the creation of gauge bosons only, but also through the tachyonic production of Higgs excitations.

Preheating Definition & Meaning - Merriam-Webster
Web26 de fev. de 2024 · This cutoff scale guarantees the perturbative analysis of this model throughout inflation and preheating, alleviating the unitarity problem of single-field Higgs inflation [19, 26,27,28] . This additional \(R^2\) term can also be induced through quantum loop corrections in the large- \(\xi \) limit. Web11 de jul. de 2024 · During inflation, we investigated the effect of the large/small on the non-gaussianity. We found that large/small could not provide the large non-gaussianity. In this paper, we divided the preheating stage to be quadratic regime and quartic regime. During the quadratic regime, the gauge bosons production is the most dominant. Web17 de ago. de 2024 · The conditions are investigated under which this model can simultaneously ensure Higgs vacuum stability up to the Planck scale, successful inflation, non-thermal Leptogenesis via the pendulum mechanism, and light neutrino masses. These can be simultaneously achieved when the scalar lepton is minimally coupled to gravity, … poppins horwich
