We consider an extension to the Standard Model (SM) with two extra real singlet scalars which both interact with the Higgs particle in the SM and one of the scalars is taken as the dark matter (DM) candidate. We show that the model successfully explains the relic abundance of the DM in the universe and evades the strong bounds from direct detection experiments while respecting the perturbativity and the vacuum stability conditions. In addition, we study the hierarchy problem within the Veltman…

Veltman Criteria in Beyond Standard Model Effective Field Theory of Complex Scalar Triplet

The Standard Model Higgs mass, not being protected by any symmetry, suffers from large correction terms due to quadratic divergence coming from the self energy corrections. Veltman Condition (V.C.)

Higgs phenomenology in the two-singlet model

A bstractWe study the phenomenology of the Standard Model (SM) Higgs sector extended by two singlet scalars. The model predicts two CP-even scalars h1,2 which are a mixture of doublet and singlet

On the Veltman Condition, the Hierarchy Problem and High-Scale Supersymmetry

In this paper we have considered the possibility that the Standard Model, and its minimal extension with the addition of singlets, merges with a high-scale supersymmetric theory at a scale satisfying

A simultaneous study of dark matter and phase transition: two-scalar scenario

The simplest extension of the Standard Model by only one real singlet scalar can explain the observed dark matter relic density while giving simultaneously a strongly first-order electroweak phase

Two Real Scalar WIMP Model in the Assisted Freeze-Out Scenario

We study a simple dark matter model given by two interacting real singlet scalars, with only one of them coupled to the Higgs. The model therefore presents a minimal assisted -freeze-out framework:

Classical scale invariance in the inert doublet model

A bstractThe inert doublet model (IDM) is a minimal extension of the Standard Model (SM) that can account for the dark matter in the universe. Naturalness arguments motivate us to study whether the

A Two-Singlet Model for Light Cold Dark Matter

We extend the standard model by adding two gauge-singlet Z{sub 2}-symmetric scalar fields that interact with visible matter only through the Higgs particle. One is a stable dark matter WIMP, and the

The hierarchy problem of the electroweak Standard Model revisited

A careful renormalization group analysis of the electroweak Standard Model, considered as a low energy effective theory, reveals that there is no hierarchy problem in the broken phase of the SM. In

Triplet-extended scalar sector and the naturalness problem

We consider the extension of the Standard Model by a complex scalar triplet field, which occurs naturally in several models of leptogenesis and see-saw mechanism for neutrino mass generation, in the
