Against Tachyophobia
John Ellis, Joel Giedt, Oleg Lebedev +2
We examine the possible extension of the parameter space of the minimal supersymmetric extension of the Standard Model (MSSM), as expressed via the renormalization-group equations…
A Gravity Dual and LHC Study of Single-Sector Supersymmetry Breaking
Maxime Gabella, Tony Gherghetta, Joel Giedt
We propose a gravitational dual of ``single-sector'' models of supersymmetry breaking which contain no messenger sector and naturally explain the scale of supersymmetry breaking an…
Lack of trinification in Z_3 orbifolds of the SO(32) heterotic string
Joel Giedt
We report results relating to the trinification scenario in some explicit string constructions that contain SU(3)^3 as a gauge symmetry. These models are obtained from symmetric Z_…
Lattice supersymmetry and string phenomenology
Joel Giedt
I discuss the usefulness of lattice supersymmetry in relation to string phenomenology. I suggest how lattice results might be incorporated into string phenomenology. I outline diff…
Heterotic Orbifolds
Joel Giedt
A review of orbifold geometry is given, followed by a review of the construction of four-dimensional heterotic string models by compactification on a six-dimensional Z_3 orbifold.…
