The quadratic divergences of the Higgs mass may be cancelled either accidentally or by the exchange of some new particles. Alternatively its impact on naturalness may be weakened by raising the Higgs mass, which requires changing the Standard Model below its natural cut-off. We show in detail how this can be achieved, while preserving perturbativity and consistency with the electroweak precision tests, by extending the Standard Model to include a second Higgs doublet that has neither a vev nor…

Almost inert Higgs bosons at the LHC
Abstract Non-minimal Higgs sectors are strongly constrained by the agreement of the measured couplings of the 125 GeV Higgs with Standard Model predictions. This agreement can be explained by an
Dark matter in the inert doublet model after the discovery of a Higgs-like boson at the LHC
A bstractWe examine the Inert Doublet Model in light of the discovery of a Higgs-like boson with a mass of roughly 126 GeV at the LHC. We evaluate one-loop corrections to the scalar masses and
Supersymmetry without a Light Higgs Boson
Motivated by the absence, so far, of any direct signal of conventional low-energy supersymmetry, we explore the consequences of making the lightest Higgs boson in supersymmetry relatively heavy, up
An updated analysis of Inert Higgs Doublet Model in light of the recent results from LUX, PLANCK, AMS-02 and LHC
In light of the recent discovery by the ATLAS and CMS experiments at the Large Hadron Collider (LHC) of a Higgs-like particle with a narrow mass range of 125–126 GeV, we perform an updated analysis
New scenario for aligned Higgs couplings originated from the twisted custodial symmetry at high energies
Abstract We investigate a new scenario of the two Higgs doublet model, where the current experimental data for the electroweak rho parameter and those for the Higgs boson couplings can be
Are there hidden scalars in LHC Higgs results?
A bstractThe Higgs boson recently discovered at the Large Hadron Collider has shown to have couplings to the remaining particles well within what is predicted by the Standard Model. The search for
LHC and dark matter signals of improved naturalness
The Standard Model Higgs suffers from the hierarchy problem, typically implying new states within the reach of the LHC. If the Higgs is very heavy ( ~ 500 GeV) the states that cutoff the quadratic
Vacuum stability in inert higgs doublet model with right-handed neutrinos
We analyze the vacuum stability in the inert Higgs doublet extension of the Standard Model (SM), augmented by right-handed neutrinos (RHNs) to explain neutrino masses at tree level by the seesaw

How can a heavy Higgs boson be consistent with the precision electroweak measurements
The fit of precision electroweak data to the Minimal Standard Model currently gives an upper limit on the Higgs boson mass of 170 GeV at 95% confidence. Nevertheless, it is often said that the Higgs
Improved Naturalness and the Two Higgs Doublet Model
The natural cutoff scale for the quadratically divergent top quark contribution to the Higgs mass parameter can be significantly raised above the surprisingly low standard model value, with important
A Combination of Preliminary Electroweak Measurements and Constraints on the Standard Model
This note presents a combination of published and preliminary electroweak results from the four LEP collaborations and the SLD collaboration which were prepared for the 1998 summer conferences.
Search for chargino and neutralino production at √s=170 and 172 GeV at LEP
A search for charginos and neutralinos, predicted by supersymmetric theories, has been performed using a data sample of 57 pb −1−1 at centre-of-mass energies of 181–184 GeV taken with the OPAL
Higgs mass bounds in a triplet model
We perform a global fit to high energy precision electroweak data in a Higgs model containing the usual isospin doublet plus a real isospin triplet. The analysis is performed in terms of the oblique
What precision electroweak physics says about the SU(6)/Sp(6) little Higgs model
We study precision electroweak constraints on the close cousin of the littlest Higgs model, the $\mathrm{SU}(6)/Sp(6)$ model. We identify a near-oblique limit in which the heavy
