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 …

I provide a pedagogical introduction to supersymmetry. The level of discussion is aimed at
readers who are familiar with the Standard Model and quantum field theory, but who have …

We show that in a general hidden sector model, supersymmetry breaking necessarily
generates at one loop a scalar and gaugino mass as a consequence of the super-Weyl …

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 consider the novel Kaluza-Klein (KK) scenario where gravity propagates in the (4+ n)-
dimensional bulk of spacetime, while gauge and matter fields are confined to the (3+ 1) …

It is shown that the effective five-dimensional theory of the strongly coupled heterotic string is
a gauged version of N= 1 five-dimensional supergravity with four-dimensional boundaries …

Abstract Models that involve extra dimensions have introduced completely new ways of
looking up on old problems in theoretical physics. The aim of the present notes is to provide …

We develop both the gravity and field theory sides of the Karch-Randall conjecture that the
near-horizon description of a certain D5-D3 brane configuration in string theory, realized as …

We propose a new possibility to reconcile the coupling unification scenario with the triplet-
doublet mass splitting based on a 5-dimensional supersymmetric model with SU (5) gauge …
