Multiplepoint principle with a scalar singlet extension of the standard model
Abstract
Here, we suggest a scalar singlet extension of the standard model, in which the multiplepoint principle (MPP) condition of a vanishing Higgs potential at the Planck scale is realized. Although there have been lots of attempts to realize the MPP at the Planck scale, the realization with keeping naturalness is quite difficult. This model can easily achieve the MPP at the Planck scale without large Higgs mass corrections. It is worth noting that the electroweak symmetry can be radiatively broken in our model. In the naturalness point of view, the singlet scalar mass should be of O(1 TeV) or less. Also, we consider righthanded neutrino extension of the model for neutrino mass generation. The model does not affect the MPP scenario, and might keep the naturalness with the new particle mass scale beyond TeV, thanks to accidental cancellation of Higgs mass corrections.

We analyze a simple extension of the standard model (SM) obtained by adding a complex singlet to the scalar sector (cxSM). We show that the cxSM can contain one or two viable cold dark matter candidates and analyze the conditions on the parameters of the scalar potential that yield the observed relic density. When the cxSM potential contains a global U(1) symmetry that is both softly and spontaneously broken, it contains both a viable dark matter candidate and the ingredients necessary for a strong first order electroweak phase transition as needed for electroweak baryogenesis. We also study the implications ofmore »

Complex singlet extension of the standard model

Gaugemediated embedding of the singlet extension of the minimal supersymmetric standard model
We embed the SMSSMa singlet extension of the minimal supersymmetric standard model with an explicit {mu}term and supersymmetric mass termin a gaugemediated supersymmetry breaking scheme. We find that by absolving the singlet of its responsibility for solving the {mu}problem, we are instead able to solve the little hierarchy problem. Specifically, we find that even with a minimal embedding of the SMSSM into a gaugemediated scheme, we can easily raise the lightest Higgs mass above 114 GeV, while keeping top squarks below the TeV scale, maintaining perturbative unification of the gauge couplings, and without tuning the other parameters of the model. 
Baryogenesis in the two doublet and inert singlet extension of the Standard Model
We investigate an extension of the Standard Model containing two Higgs doublets and a singlet scalar field (2HDSM). We show that the model can have a strongly firstorder phase transition and give rise to the observed baryon asymmetry of the Universe, consistent with all experimental constraints. In particular, the constraints from the electron and neutron electric dipole moments are less constraining here than in pure twoHiggsdoublet model (2HDM). The twostep, firstorder transition in 2HDSM, induced by the singlet field, may lead to strong supercooling and low nucleation temperatures in comparison with the critical temperature, T{sub n}≪T{sub c}, which can significantlymore » 
LHC benchmark scenarios for the real Higgs singlet extension of the standard model
Here, we present benchmark scenarios for searches for an additional Higgs state in the real Higgs singlet extension of the Standard Model in Run 2 of the LHC. The scenarios are selected such that they ful ll all relevant current theoretical and experimental constraints, but can potentially be discovered at the current LHC run. We take into account the results presented in earlier work and update the experimental constraints from relevant LHC Higgs searches and signal rate measurements. The benchmark scenarios are given separately for the low mass and high mass region, i.e. the mass range where the additional Higgsmore »Cited by 24
