A broad overview of the current status of proton stability in unified models of particle
interactions is given which includes non-supersymmetric unification, SUSY and SUGRA …

We review the theoretical foundations and the most important physical applications of the
Pinch Technique (PT). This general method allows the construction of off-shell Green's …

We show that the bound from the electroweak data on the size of extra dimensions
accessible to all the standard model fields is rather loose. These “universal” extra …

Five-dimensional models where the bulk is a slice of AdS have the virtue of solving the
hierarchy problem. The electroweak scale is generated by a “warp” factor of the induced …

We explore the consequences of placing the Standard Model gauge fields in the bulk of the
recently proposed localized gravity model of Randall and Sundrum. We find that the Kaluza …

The phenomenology of the Randall-Sundrum model of localized gravity is analyzed in detail
for the two scenarios where the standard model (SM) gauge and matter fields are either …

We consider the possibility of gauge bosons living in the recently proposed five-dimensional
theory with localized gravity. We study the mass spectrum of the Kaluza-Klein (KK) …

Physics at the Large Hadron Collider (LHC) and the International e+ e-Linear Collider (ILC)
will be complementary in many respects, as has been demonstrated at previous generations …

Abstract An SU (3)× SU (2)× U (1) supersymmetric theory is constructed with a TeV-sized
extra dimension compactified on the orbifold S 1/(Z 2× Z 2′). The compactification breaks …

We present models in which the observed fermion masses and mixings are generated by
dynamically localizing the three generations of matter in a flat compact extra dimension. We …
