Hierarchy problem, gauge coupling unification at the Planck scale, and vacuum stability
Naoyuki Haba, Hiroyuki Ishida, Ryo Takahashi +1
From the point of view of the gauge hierarchy problem, introducing an intermediate scale in addition to TeV scale and the Planck scale (…
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…
Axion monodromy inflation with multi-natural modulations
Tetsutaro Higaki, Tatsuo Kobayashi, Osamu Seto +1
We study parameter space in the axion monodromy inflation corrected by dynamically generated terms involving with the axion. The potential has the linear potential with multiple si…
Axion monodromy inflation with sinusoidal corrections
Tatsuo Kobayashi, Osamu Seto, Yuya Yamaguchi
We study the axion monodromy inflation with a non-perturbatively generated sinusoidal term. The potential form is a mixture between the natural inflation and the axion monodromy in…
Accurate renormalization group analyses in neutrino sector
Naoyuki Haba, Kunio Kaneta, Ryo Takahashi +1
We investigate accurate renormalization group analyses in neutrino sector between -oscillation and seesaw energy scales. We consider decoupling effects of top quark and Higgs bo…
Neutrino mass from neutrinophilic Higgs and leptogenesis
Naoyuki Haba, Osamu Seto, Yuya Yamaguchi
In a class of two Higgs doublet model, where one Higgs doublet generates masses of quarks and charged leptons whereas the other Higgs doublet with a tiny vacuum expectation value (…
