Model
In models with universal extra dimensions, all Standard Model particles are promoted to five dimensional fields which extend into a flat extra dimension S^1/Z_2. The inclusion of extra dimensional fermion mass terms splits the mass of the Kaluza-Klein fermion modes from Kaluza-Klein masses of the gauge bosons and the Higgs which has important implications for the collider- and the dark matter...

Model
We propose a six dimensional Universal Extra Dimensions (UED) model compactified on a real projective plane $RP2$, a two-sphere with its antipodal points being identified. We utilize the Randjbar-Daemi-Salam-Strathdee spontaneous sphere compactification with a monopole configuration of an extra $U(1)_X$ gauge field that leads to a spontaneous radius stabilization. Unlike the sphere and the...

Model
We discuss the modulus stabilization by the Casimir energy in a gauge-Higgs unification model in the warped spacetime. We evaluate the masses of the radion and the Higgs boson and mixing between them. We also consider effects of brane-localized kinetic and mass terms on the stabilization.

Model
We show that it is possible to create an RS soft-wall model,
a model with a compact extra dimension, without using fundamental
branes. All that is required are bulk scalar fields minimally
coupled to gravity. Of crucial importance is the stability of
the size of the extra dimension. Without branes, one cannot
easily implement the Goldberger-Wise mechanism, and instead it
must be shown...

Model
Lepton number violating processes are a typical problem in theories
with a low quantum gravity scale. Here
we examine lepton number violation in theories with a saturated black
hole bound on a large number of species. Such theories have been
advocated recently as a possible solution
to the hierarchy problem and an explanation of the smallness of neutrino
masses. Naively one would...
