Multiple-point principle with a scalar singlet extension of the standard model
- Physics
- 2016
We suggest a scalar singlet extension of the standard model, in which the multiple-point principle (MPP) condition of a vanishing Higgs potential at the Planck scale is realized. Although there have…
Problems of the Standard Model and their relations to Planck/String scale physics
- Physics
- 2017
Since the discovery of the Higgs boson [1, 2], we are now living in an exciting era: We already know all the Standard Model (SM) particles and their couplings ! In particular, the observed quartic…
Criticality and Inflation of the Gauged B-L Model
- Physics
- 2015
We consider the multiple point principle (MPP) and the inflation of the gauged B-L extension of the Standard Model (SM) with a classical conformality. We examine whether the scalar couplings and…
RG-improvement of the effective action with multiple mass scales
- PhysicsJournal of High Energy Physics
- 2018
Improving the effective action by the renormalization group (RG) with several mass scales is an important problem in quantum field theories. A method based on the decoupling theorem was proposed in…

Millicharge or decay: a critical take on Minimal Dark Matter
- Physics
- 2015
Minimal Dark Matter (MDM) is a theoretical framework highly appreciated for its minimality and yet its predictivity. Of the two only viable candidates singled out in the original analysis, the scalar…
A radiative model for the weak scale and neutrino mass via dark matter
- Physics
- 2015
A bstractWe present a three-loop model of neutrino mass in which both the weak scale and neutrino mass arise as radiative effects. In this approach, the scales for electroweak symmetry breaking, dark…
Saddle point inflation in string-inspired theory
- Physics, Economics
- 2015
The observed value of the Higgs mass indicates the possibility that there is no supersymmetry below the Planck scale and that the Higgs can play the role of the inflaton. We examine the general…

Recent results from ATLAS and CMS point to a narrow range for the Higgs mass: M_H∈(124,126) GeV. Given this range, a case may be made for new physics beyond the Standard Model (SM) because of the…
Vanishing Higgs potential at the Planck scale in a singlet extension of the standard model

The discovery of the Higgs by ATLAS and CMS at the LHC not only provided the last missing building block of the electroweak Standard Model, the mass of the Higgs has been found to have a very…
Minimal Higgs inflation

We consider a possibility that the Higgs field in the Standard Model (SM) serves as an inflaton when its value is around the Planck scale. We assume that the SM is valid up to an ultraviolet cutoff…
Predictions on mass of Higgs portal scalar dark matter from Higgs inflation and flat potential

A bstractWe consider the Higgs portal Z2 scalar model as the minimal extension of the Standard Model (SM) to incorporate the dark matter. We analyze this model by using the two-loop renormalization…
TeV-scale B − L model with a flat Higgs potential at the Planck scale: In view of the hierarchy problem

The recent discovery of the Higgs-like particle at around 126 GeV has given us a big hint towards the origin of the Higgs potential. Especially the running quartic coupling vanishes near the Planck…
Extending Higgs inflation with TeV scale new physics
