Higgs Criticality in a Viable Motivated Model

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,

Standard Model—axion—seesaw—Higgs portal inflation. Five problems of particle physics and cosmology solved in one stroke

We present a minimal extension of the Standard Model (SM) providing a consistent picture of particle physics from the electroweak scale to the Planck scale and of cosmology from inflation until

Warm inflation, neutrinos and dark matter: a minimal extension of the Standard Model

Abstract We show that warm inflation can be realized within a minimal extension of the Standard Model with three right-handed neutrinos, three complex scalars and a gauged lepton/B-L U(1) symmetry.

Neutrino-axion-dilaton interconnection

We show that a recently proposed framework that provides a simple connection between Majorana neutrinos and an invisible axion in minimal scalar extensions of the standard electroweak model can be

Several Problems in Particle Physics and Cosmology Solved in One SMASH

The Standard Model (SM) of particle physics is a big success. However, it lacks explanations for cosmic inflation, the matter-anti-matter asymmetry of the Universe, dark matter, neutrino

Neutrino mass and asymmetric dark matter: study with inert Higgs doublet and high scale validity

We consider an inert Higgs doublet (IHD) extension of the Standard Model accompanied with three right handed neutrinos and a dark sector, consisting of a singlet fermion and a scalar, in order to

A minimal scale invariant axion solution to the strong CP-problem

We present a scale-invariant extension of the Standard model allowing for the Kim-Shifman-Vainstein-Zakharov (KSVZ) axion solution of the strong CP problem in QCD. We add the minimal number of new

Assessing perturbativity and vacuum stability in high-scale leptogenesis

A bstractWe consider the requirements that all coupling constants remain perturbative and the electroweak vacuum metastable up to the Planck scale in high-scale thermal leptogenesis, in the context

Invisible Axions and Light NEUTRINOS—ARE they Connected?

Physical arguments involving the solar neutrino problem are given which connect the scale of U(1)PQ breakdown with that of the spontaneous breakdown of lepton number. In the simplest model, the

Unifying inflation and dark matter with neutrino masses.

We propose a simple model where a gauge-invariant inflaton is responsible for cosmic inflation and generates the seed for structure formation, while its relic thermal abundance explains the missing

A-term inflation and the smallness of the neutrino masses

The smallness of the neutrino masses may be related to inflation. The minimal supersymmetric standard model (MSSM) with small neutrino Yukawa couplings already has all the necessary ingredients for a

Chiral asymmetry from a 5D Higgs mechanism

An intriguing feature of the Standard Model is that the representations of the unbroken gauge symmetries are vector-like whereas those of the spontaneously broken gauge symmetries are chiral. Here we

Stabilization of the electroweak vacuum by a scalar threshold effect

A bstractWe show how a heavy scalar singlet with a large vacuum expectation value can evade the potential instability of the Standard Model electroweak vacuum. The quartic interaction between the

Baryogenesis via neutrino oscillations

We propose a new mechanism of leptogenesis in which the asymmetries in lepton numbers are produced through the $\mathrm{CP}$-violating oscillations of ``sterile'' (electroweak singlet) neutrinos. The

Sterile neutrinos as dark matter.

TLDR
This model is reexamine and it is found that hot, warm, and cold dark matter are all possibilities and the number density of sterile neutrinos is proportional to [mu][sup 2]/M so that the energy density today is independent of M, which is crucial in determining the large scale structure of the Universe.
