We consider the introduction of a complex scalar field carrying a global lepton number charge to the Standard Model and the Higgs inflation framework. The conditions are investigated under which this model can simultaneously ensure Higgs vacuum stability up to the Planck scale, successful inflation, non-thermal Leptogenesis via the pendulum mechanism, and light neutrino masses. These can be simultaneously achieved when the scalar lepton is minimally coupled to gravity, that is, when standard… Expand

Spontaneous leptogenesis in Higgs inflation
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 theExpand
Quintessential Inflation with Dynamical Higgs Generation as an Affine Gravity
First, we propose a scale-invariant modified gravity interacting with a neutral scalar "inflaton" and a Higgs-like SU(2)xU(1) iso-doublet scalar field based on the formalism of non-RiemannianExpand
Quintessential Inflation with Dynamical Higgs Generation as an Affine Gravity
TLDR
A scale-invariant modified gravity interacting with a neutral scalar "inflaton" and a Higgs-like SU(2)xU(1) iso-doublet scalar field based on the formalism of non-Riemannian (metric-independent) spacetime volume-elements to describe a quintessential inflationary scenario. Expand
Stochastic baryogenesis
Using a multi-field stochastic approach, we investigate the vacuum expectation value (VEV) during inflation of a scalar field charged under a mildly broken global U(1) symmetry that can play the roleExpand

Living beyond the edge: Higgs inflation and vacuum metastability
The measurements of the Higgs mass and top Yukawa coupling indicate that we live in a very special universe, at the edge of the absolute stability of the electroweak vacuum. If fully stable, theExpand
Unitarizing Higgs Inflation
Abstract We consider a simple extension of the Standard Model Higgs inflation with one new real scalar field which preserves unitarity up to the Planck scale. The new scalar field (called sigma)Expand
Higgs inflation: consistency and generalisations
We analyse the self-consistency of inflation in the Standard Model, where the Higgs field has a large non-minimal coupling to gravity. We determine the domain of energies in which this modelExpand

An extension of the Standard Model with three right-handed neutrinos and a simple invisible axion model can account for all experimentally confirmed signals of new physics (neutrino oscillations,Expand
On stability of the electroweak vacuum and the Higgs portal
In the Standard Model (SM), the Higgs mass around 125 GeV implies that the electroweak vacuum is metastable since the quartic Higgs coupling turns negative at high energies. I point out that a tinyExpand
Distinguishing between R-2-inflation and Higgs-inflation
Abstract We present three features which can be used to distinguish the R 2 -inflation Higgs-inflation from with ongoing, upcoming and planned experiments, assuming no new physics (apart form sterileExpand
Higgs-Inflaton Mixing and Vacuum Stability
Abstract The quartic and trilinear Higgs field couplings to an additional real scalar are renormalizable, gauge and Lorentz invariant. Thus, on general grounds, one expects such couplings between theExpand
