INFLATON FIELD AND PRIMORDIAL BLACKHOLE [PDF]
International Journal of Modern Physics D, 2002 Primordial black hole formation has been studied using an inflaton field with a variable cosmological term as the potential.

Running non-minimal inflation with stabilized inflaton potential
European Physical Journal C: Particles and Fields, 2017 In the context of the Higgs model involving gauge and Yukawa interactions with the spontaneous gauge symmetry breaking, we consider $$\lambda \phi ^4$$ λ ϕ 4 inflation with non-minimal gravitational coupling, where the Higgs field is identified as the ...

Shrinking the Warm Little Inflaton
Journal of High Energy Physics, 2023 We show that warm inflation can be successfully realized in the high temperature regime through dissipative interactions between the inflaton and a single fermionic degree of freedom, provided that the latter’s mass is an oscillatory function of the ...

Inflatonic baryogenesis with large tensor mode
Physics Letters B, 2015 We consider a complex inflaton field with a CP asymmetric term for its potential. This CP asymmetric term produces the global charge of the inflaton after inflation.

Pre-heating in the framework of massive gravity
Nuclear Physics B, 2016 In this paper we propose a mechanism of natural pre-heating of our universe by introducing an inflaton field dependent mass term for the gravitational wave for a specific class of massive gravity theory.

Reheating after inflation by supersymmetry breaking
European Physical Journal C: Particles and Fields, 2021 We study reheating after the end of inflation in models where the inflaton is the superpartner of goldstino and is charged under a gauged U(1) R-symmetry. We consider two classes of models – one is small field characterized by an almost flat Kähler space,

Simple sinflaton-less α-attractors
Journal of High Energy Physics, 2019 We construct the simplest inflationary α-attractor models in supergravity: it has only one scalar, the inflaton. There is no sinflaton since the inflaton belongs to an orthogonal nilpotent superfield where the sinflaton depends on fermion bilinears. When

Higgs Chaotic Inflation in Standard Model and NMSSM
, 2010 We construct a chaotic inflation model in which the Higgs fields play the role of the inflaton in the standard model as well as in the singlet extension of the supersymmetric standard model.

Non-Gaussianity from Particle Production during Inflation
Advances in Astronomy, 2010 In a variety of models the motion of the inflaton may trigger the production of some non-inflaton particles during inflation, for example via parametric resonance or a phase transition.
