We consider extra dimensional gauge theories on an interval. We first review the derivation of the consistent boundary conditions (BC’s) from the action principle. These BC’s include choices that give rise to breaking of the gauge symmetries. The boundary conditions could be chosen to coincide with those commonly applied in orbifold theories, but there are(More)
In models with dynamical supersymmetry breaking in the hidden sector, the gaugino masses in the observable sector have been believed to be extremely suppressed (below 1 keV), unless there is a gauge singlet in the hidden sector with specific couplings to the observable sector gauge multiplets. We point out that there is a pure supergravity contribution to(More)

We find the phase and flavor symmetry breaking pattern of each N = 1 supersymmetric vacuum of SU(nc) and USp(2nc) gauge theories, constructed from the exactly solvable N = 2 theories by perturbing them with small adjoint and generic bare hypermultiplet (quark) masses. In SU(nc) theories with nf ≤ nc the vacua are labelled by an integer r, in which the(More)
We present a simple model of gauge mediation (GM) which does not have a messenger sector or gauge singlet fields. The standard model gauge groups couple directly to the sector which breaks supersymmetry dynamically. This is the first phenomenologically viable example of this type in the literature. Despite the direct coupling, the model can preserve(More)

We present a calculable supersymmetric theory of a composite “fat” Higgs boson. Electroweak symmetry is broken dynamically through a new gauge interaction that becomes strong at an intermediate scale. The Higgs mass can easily be 200–450 GeV along with the superpartner masses, solving the supersymmetric little hierarchy problem. We explicitly verify that(More)
We show that in see-saw models of neutrino mass à la SUSY SO(10), the observed large mixing in atmospheric neutrinos naturally leads to large b− s transitions. If the associated new CP phase turns out to be large, this SUSY contributions can drastically affect the CP violation in some of the B decay channels yielding the β and γ angles of the unitarity(More)
