On preheating in higgs inflation

WebWe use a semiclassical lattice approach to perform the first nonlinear study of preheating in R2-healed Higgs inflation, in the “R2-like” regime where the curvature-squared coupling β and nonminimal coupling ξ of the Higgs field contribute similarly to the CMB scalar perturbations. Preheating occurs first through tachyonic production of Higgs bosons, … Web24 de mar. de 2024 · We study preheating following Higgs inflation in the Palatini formulation of gravity.

Web17 de abr. de 2015 · In the Palatini formulation, the field re-enters the very flat inflationary plateau during preheating, leading to new periods of inflation, and preheating takes less than one e-fold [194,195]. ... 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. can i make my own shimeji https://mans-item.com

The situation may be … 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.

Web8 de mar. de 2024 · We propose a scenario of spontaneous leptogenesis in Higgs inflation with help from two additional operators: the Weinberg operator (Dim 5) and the derivative coupling of the Higgs field and the current of lepton number (Dim 6). The former is responsible for lepton number violation and the latter induces chemical potential for … 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.
