Anarchy and hierarchy
- N. Haba, H. Murayama
- Physics
- 14 September 2000
We advocate a new approach to study models of fermion masses and mixings, namely anarchy proposed in Ref. [1]. In this approach, we scan the O(1) coefficients randomly. We argue that this is the… Expand
Electroweak symmetry breaking in supersymmetric gauge-Higgs unification models
- Kiwoon Choi, N. Haba, K. Jeong, Ken-ichi Okumura, Y. Shimizu, M. Yamaguchi
- Physics
- 15 December 2003
We examine the Higgs mass parameters and electroweak symmetry breaking in supersymmetric orbifold field theories in which the 4-dimensional Higgs fields originate from higher-dimensional gauge… Expand

ϵ′/ϵ anomaly and neutron EDM in SU(2)L × SU(2)R × U(1)B−L model with charge symmetry
- N. Haba, Hiroyuki Umeeda, T. Yamada
- Physics
- 27 February 2018
A bstractThe Standard Model prediction for ϵ′/ϵ based on recent lattice QCD results exhibits a tension with the experimental data. We solve this tension through WR+ gauge boson exchange in the SU(2)L… Expand
Planck scale boundary conditions in the standard model with singlet scalar dark matter
- N. Haba, K. Kaneta, R. Takahashi
- Physics
- 7 December 2013
A bstractWe investigate Planck scale boundary conditions on the Higgs sector of the standard model with a gauge singlet scalar dark matter. We will find that vanishing selfcoupling and Veltman… Expand
Universally Leptophilic Dark Matter From Non-Abelian Discrete Symmetry
- N. Haba, Y. Kajiyama, Shigeki Matsumoto, H. Okada, K. Yoshioka
- Physics
- 27 August 2010
Abstract The positron anomaly recently reported by the cosmic-ray measurements can be explained by the decaying dark matter scenario, where it decays mainly into leptons with the lifetime of O ( 10… Expand
Simple model of direct gauge mediation of metastable supersymmetry breaking
We construct a model of direct gauge mediation of metastable supersymmetry breaking by simply deforming the Intriligator, Seiberg, and Shih model in terms of a dual meson superpotential mass term. No… Expand
Multiple-point principle with a scalar singlet extension of the standard model
- N. Haba, Hiroyuki Ishida, N. Okada, Y. Yamaguchi
- Physics
- 30 July 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… Expand
Multiple-point principle realized with strong dynamics
We present a novel extension of the Standard Model which fulfills the multiple-point principle without contradicting the Higgs particle mass measurement. In the model, the scalar potential has two… Expand
