Alchemical inflation: inflaton turns into Higgs [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2012
We propose a new inflation model in which a gauge singlet inflaton turns into the Higgs condensate after inflation. The inflationary path is characterized by a moduli space of supersymmetric vacua spanned by the inflaton and Higgs field. The inflation energy scale is related to the soft supersymmetry breaking, and the Hubble parameter during inflation ...

Non-minimal Higgs inflation in the context of warm scenario in the light of Planck data

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We investigate the non-minimally Higgs inflaton (HI) model in the context of warm inflation scenario. Warm little inflaton (WLI) model considers the little Higgs boson as inflaton.

Non-minimally coupled quartic inflation with Coleman-Weinberg one-loop corrections in the Palatini formulation

open access: yesPhysics Letters B, 2020
We discuss how the non-minimal coupling ξϕ2R between the inflaton and the Ricci scalar affects the predictions of single field inflation models in the Palatini formalism.

Candidates for Inflaton in Quiver Gauge Theory

open access: yes, 2004
The inflaton necessary to implement the mechanism of inflationary cosmology has natural candidates in quiver gauge theory. We discuss the dimensionless coefficients of quartic couplings and enumerate scalars which are singlet under the low-energy gauge ...

Higgs boson and inflation

open access: yes上海师范大学学报. 自然科学版, 2014
Higgs is the only scalar particle that already observed up to now.In the standard model of particle physics,Higgs plays a very important role.On the other hand,inflation is also driven by scalar field called inflaton.Higgs boson can not be the inflaton ...

Modulated Inflation (@SUSY08)

open access: yes, 2008
We consider cosmological perturbations caused by modulated inflaton velocity. During inflation, the inflaton motion is damped and the velocity is determined by the parameters such as couplings or masses that may depend on light fields(moduli). The number

Late Reheating, Hadronic Jets and Baryogenesis [PDF]

open access: yes, 2003
If inflaton couples very weakly to ordinary matter the reheating temperature of the universe can be lower than the electroweak scale. In this letter we show that the late reheating occurs in a highly non-uniform way, within narrow areas along the jets ...

Density Fluctuations in the Oscillatory Phase of Nonclassical Inflaton in FRW Universe

open access: yes, 2007
Using coherent and squeezed state formalisms of quantum optics for a minimally coupled non-classical inflaton in the FRW mertic is studied, in semiclassical theory of gravity.
