Observable Gravity Waves From U(1)_ Higgs and Coleman-Weinberg Inflation
Nobuchika Okada, Qaisar Shafi
We present a realistic non-supersymmetric inflation model based on a gauged U(1) symmetry and a tree-level Higgs potential. The inflaton is identified with the scalar field…
Supersymmetric B-L inflation near the conformal coupling
Masato Arai, Shinsuke Kawai, Nobuchika Okada
We investigate a novel scenario of cosmological inflation in a gauged extended minimal supersymmetric Standard Model with R-symmetry. We use a noncanonical Kähler potential a…
125 GeV Higgs Boson and TeV Scale Colored Fermions in Gauge-Higgs Unification
Nobuhito Maru, Nobuchika Okada
In the context of a simple gauge-Higgs unification scenario based on the gauge group SU(3) times U(1)' in a 5-dimensional flat spacetime, we investigate a possibility to realize th…
Gamma ray emission in Fermi bubbles and Higgs portal dark matter
Nobuchika Okada, Osamu Seto
It has been recently pointed out that the excess of the gamma ray spectrum in the Fermi Bubbles at low latitude can be well explained by the annihilation of dark matter particles.…
125 GeV Higgs Boson From Gauge-Higgs Unification: A Snowmass white paper
Ilia Gogoladze, Nobuchika Okada, Qaisar Shafi
In certain five dimensional gauge theories compactified on the orbifold the Standard Model Higgs doublet is identified with the zero mode of the fifth component of the ga…
H to Z gamma in Gauge-Higgs Unification
Nobuhito Maru, Nobuchika Okada
In our previous paper, we have investigated effects of a simple gauge-Higgs unification model on the diphoton signal events from the Higgs boson production at the Large Hadron Coll…
