Non-thermal Higgs Spectrum in Reheating Epoch: Primordial Condensate vs. Stochastic Fluctuation
Kunio Kaneta, Kin-ya Oda
Since electroweak symmetry is generally broken during inflation, the Standard Model Higgs field can become supermassive even after the end of inflation. In this paper, we study the…
Quantifying Limits on CP Violating Phases from EDMs in Supersymmetry
Kunio Kaneta, Natsumi Nagata, Keith A. Olive +2
We revisit the calculation of the electron, neutron, and proton electric dipole moments (EDMs) in the constrained minimal supersymmetric standard model (CMSSM). The relatively larg…
Portal Connecting Dark Photons and Axions
Kunio Kaneta, Hye-Sung Lee, Seokhoon Yun
The dark photon and the axion (or axion-like particle) are popular light particles of the hidden sector. Each of them has been actively searched for through the couplings called th…
Coupling Unification and Dark Matter in a Standard Model Extension with Adjoint Majorana Fermions
Tasuku Aizawa, Masahiro Ibe, Kunio Kaneta
We revisit an extension of the Standard Model with Majorana fermions in the adjoint representations. There, a precise coupling unification and the good candidate for dark matter (t…
New resonance scale and fingerprint identification in minimal composite Higgs models
Shinya Kanemura, Kunio Kaneta, Naoki Machida +1
Composite Higgs models are an intriguing scenario in which the Higgs particle is identified as a pseudo Nambu-Goldstone boson associated with spontaneous breaking of some global sy…
Gravitational effects on vanishing Higgs potential at the Planck scale
Naoyuki Haba, Kunio Kaneta, Ryo Takahashi +1
We investigate gravitational effects on the so-called multiple point criticality principle (MPCP) at the Planck scale. The MPCP requires two degenerate vacua, whose necessary condi…
