We consider the triple coupling of the Higgs boson in the context of the
gauge-Higgs unification scenario. We show that the triple coupling of the Higgs
boson in this scenario generically deviates from SM prediction since the Higgs
potential in th...

We propose a new model of 5D gauge-Higgs unification
with a successful electroweak symmetry breaking and a realistic Higgs boson
mass. In our model, the representations of the fermions are very simple, the
${\bf 3}, \overline...

A new vector dark matter (DM) scenario in the context of the gauge-Higgs
unification (GHU) is proposed. The DM particle is identified with an
electric-charge neutral component in an doublet vector field with the
same quantum number as th...

We propose a Minimal Dark Matter (MDM) scenario in the context of a simple
gauge-Higgs Unification (GHU) model based on the gauge group SU(3) x U(1)' in
5-dimensional Minkowski space with a compactification of the 5th dimension on
S^1/Z_2 orbifold...

We propose a Majorana fermion dark matter in the context of a simple
gauge-Higgs Unification (GHU) scenario based on the gauge group x
in 5-dimensional Minkowski space with a compactification of the 5th
dimension on orbif...
