“…In addition, there are the various Higgs mass bounds from accelerator experiments. The direct LEP search [25] gives a lower bound of 114.4 GeV, while a fit to electroweak precision data prefers [26] a mass m h < 182 GeV. Finally, a combined CDF and DO analysis of Tevatron data [27] excludes the range 160 GeV < m h < 170 GeV.…”

Standard model Higgs boson-inflaton and dark matter

The standard model Higgs boson can serve as the inflaton field of slow roll inflationary models provided it exhibits a large non-minimal coupling with the gravitational scalar curvature. The Higgs boson self interactions and its couplings with a standard model singlet scalar serving as the source of dark matter are then subject to cosmological constraints. These bounds, which can be more stringent than those arising from vacuum stability and perturbative triviality alone, still allow values for the Higgs boson mass which should be accessible at the LHC. As the Higgs boson coupling to the dark matter strengthens, lower values of the Higgs boson mass consistent with the cosmological data are allowed.

“…This scenario, in which the usual SM fields are supplemented by a single scalar SU(2) doublet which does not contribute to electroweak-symmetry breaking (EWSB) and couples to the gauge-boson sector but not the fermion sector, has a wealth of potential phenomenological applications. Perhaps the most intriguing of these stems from the recent observation [2] that the fields of this additional scalar doublet can provide a positive contribution to the oblique T parameter [3] sufficient to render a SM Higgs mass of m h = 400 − 600 GeV consistent with precision data [4]. A host of other potential applications for inert 1 doublets exist as well.…”

Dilepton signals in the inert doublet model

The Inert Doublet Model is one of the simplest and most versatile scenarios for physics beyond the Standard Model. In this work, we examine the prospects for detecting the additional fields of this model at the LHC in the dilepton channel. We investigate a wide variety of theoreticallyand phenomenologically-motivated benchmark scenarios, and show that within regions of model parameter space in which the dark-matter candidate is relatively light (between 40 and 80 GeV) and the mass splitting between the neutral scalars is also roughly 40 − 80 GeV, a signal at the 3σ to 12σ significance level can be observed with 100 fb −1 of integrated luminosity. In addition, even if the mass splitting between the neutral scalars is larger than M Z , a signal of more than 3σ can be observed as long as the mass of the dark-matter candidate is around 40 GeV.

“…This model was originally proposed [1] for its applications to neutrino physics. However, the recent observation [2] that the presence of an inert doublet can provide the necessary correction to the oblique S and T parameters [3] to accommodate a heavy Higgs boson, with a mass as high as 400 − 600 GeV, without running afoul of LEP constraints [4] has stimulated a great deal of renewed interest in the model. Since then, the IDM has found a host of additional applications to subjects as diverse as neutrino physics [5], electroweak-symmetry breaking [6], and grand unification [7].…”
