MSSM from Ads/CFT
We develop a robust version of the MSSM from a orbifolded AdS/CFT,
with natural low scale unification and briefly discuss cosmology in this
testable model.Comment: 12 pages latex and one eps figur
Proton Decay Constraints on Low Scale AdS/CFT Unification
Dark matter candidates and proton decay in a class of models based on the
AdS/CFT correspondence are discussed. We show that the present bound on the
proton decay lifetime is inconsistent with SUSY, and strongly
constrains non-SUSY, low scale trinification type unification of
orbifolded AdS models.Comment: 10 page
Construction of multi-instantons in eight dimensions
We consider an eight-dimensional local octonionic theory with the
seven-sphere playing the role of the gauge group. Duality conditions for two-
and four-forms in eight dimensions are related. Dual fields--octonionic
instantons--solve an 8D generalization of the Yang-Mills equation. Modifying
the ADHM construction of 4D instantons, we find general -instanton 8D
solutions which depends on effective parameters
Spontaneous Breaking of Gauge Groups to Discrete Symmetries
Many models of beyond Standard Model physics connect flavor symmetry with a
discrete group. Having this symmetry arise spontaneously from a gauge theory
maintains compatibility with quantum gravity and can be used to systematically
prevent anomalies. We minimize a number of Higgs potentials that break gauge
groups to discrete symmetries of interest, and examine their scalar mass
spectra.Comment: 45 page
