Warm inflation with an oscillatory inflaton in the non-minimal kinetic coupling model

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In the cold inflation scenario, the slow roll inflation and reheating via coherent rapid oscillation, are usually considered as two distinct eras. When the slow roll ends, a rapid oscillation phase begins and the inflaton decays to relativistic particles

Inflaton as a pseudo-Nambu-Goldstone boson

open access: yesPhysics Letters B, 2023
In the realistic model of cosmic inflation the inflaton potential should be flat and stable under quantum corrections. It is natural to imagine that there is some symmetry behind and an idea of the inflaton as a Nambu-Goldstone boson of spontaneous ...

Nonminimally-coupled warm Higgs inflation: Metric vs. Palatini formulations

open access: yesNuclear Physics B, 2023
In this work, we study the non-minimally-coupled Higgs model in the context of warm inflation scenario on both metric and Palatini approaches. We particularly consider a dissipation parameter of the form Γ=CTT with CT being a coupling parameter and focus

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.

Theoretical and observational prescription of warm-inflation in FLRW universe with torsion

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The paper deals with Warm Inflationary scenario in FLRW with torsion both from theoretical and observational point of view. In the background of flat FLRW model the Hubble parameter is found to be proportional to the torsion function and warm inflation ...

Does fractal universe favour warm inflation: Observational support?

open access: yesNuclear Physics B, 2022
The present work examines the possibility of warm inflationary paradigm in the modified gravity theory with fractal geometry. By choosing the normal fluid as radiation fluid and the effective fluid (with the extra term in modified field equation) as the ...

Primordial black-hole dark matter via warm natural inflation

open access: yesPhysics Letters B, 2022
We report on a study of the natural warm inflationary paradigm (WNI). We show two important new results arise in this model. One is that the observational constraints on the primordial power spectrum from the cosmic microwave background (CMB) can be ...
