Web1 de out. de 2024 · Download PDF Abstract: We perform an extensive analysis of linear fluctuations during preheating in Higgs inflation in the Einstein frame, where the fields are minimally coupled to gravity, but the field-space metric is nontrivial. The self-resonance of the Higgs and the Higgsed gauge bosons are governed by effective masses that scale … WebRecent analyses of cosmological data suggest the presence of an extra relativistic component beyond the Standard Model content. The Higgs-Dilaton cosmological model …

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 … WebSoon after the end of inflation, the field oscillates, leading to the creation of particles in a process called reheating. If reheating begins with parametric resonance, the process is called preheating. New Higgs Inflation presumes that the Higgs field is the scalar field in question, involving a characteristic non-minimal "derivative" coupling.
WebRecently, the problem of unitarity violation during the preheating stage of Higgs inflation with a large non-minimal coupling has been much discussed in the literature. We point … WebSpacetime torsion is known to be highly suppressed at the end of inflation, which is called preheating. This result was recently shown in (EPJ C (2024)) in the frame of Einstein–Cartan–Brans–Dicke inflation. In this paper, it is shown that a torsionful magnetogenesis in QED effective Lagrangean drives a torsion damping in order to be …

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. shapes printable coloring pagesWeb6 de set. de 2024 · We study preheating following Higgs inflation in the Palatini formulation of gravity.
