Scherk-Schwarz orbifolds at the LHC
Abstract
We examine orbifold theories of grand unification with Scherk-Schwarz twisting, performing a renormalization group analysis and applying low energy experimental constraints. We rule out the minimal SU(5) models, and consider simple extensions including additional fields, such as an additional scalar field, or additional symmetries, such as SU(5)×U(1) or E6. We find that it is very difficult to generate a large enough Higgs mass while simultaneously passing LHC experimental search constraints.
