Web18 de mai. de 2024 · We study the post-inflationary dynamics for reheating and freeze-in dark matter in the Higgs-R2 inflation model. Taking the perturbative approach for reheating, we determine the evolution of the temperature for radiation bath produced during reheating and determine the maximum and reheating temperatures of the Universe. … 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.
Web1 de fev. de 2024 · We study particle production at the preheating era in inflation models with nonminimal coupling ξφ{sup 2} R and quartic potential λφ{sup 4}/4 for several cases: real scalar inflaton, complex scalar inflaton and Abelian Higgs inflaton. We point out that the preheating proceeds much more violently than previously thought. 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 …

We review the recent progress in Higgs inflation focusing on Higgs- … WebMotivated by a recent discussion about the role of flat directions, a typical feature of supersymmetric models, in the process of particle production in the early universe a consistent model of inflation and preheating in supergravity with MSSM fields has been built. It is based on a model proposed by M. Kawasaki, M. Yamaguchi and T. Yanagida. …
