Abstract

We investigate models of supersymmetric grand unification based on the gauge group SU(5). We consider models with non-universal gaugino masses and confront them with low energy constraints, including the Higgs boson mass and the Dark Matter relic density. We also discuss fine-tuning and show the effect of not including the mu-parameter into fine tuning determinations. With this relaxation, we find viable scenarios with low fine tuning and study some model choices for gaugino mass ratios. We demonstrate that some orbifold inspired models may provide low fine-tuning and the preferred relic abundance of Dark Matter while evading all experimental constraints. We present benchmarks that should be explored at the LHC and future colliders.
