Gauge Coupling Unification in Gauge-Higgs GUT: Theory and Phenomenology

This paper explores the unification of gauge couplings within the framework of Gauge-Higgs Grand Unified Theories (GUTs) in a 5D Anti-de Sitter space. It addresses the potential to solve Standard Model puzzles like the Higgs mass and fermion hierarchies, while also predicting observable signatures at the LHC. The use of Planck-brane correlators for consistent coupling evolution is a key methodological aspect, allowing for a more accurate analysis than previous approaches. The paper revisits and supplements existing results, including brane masses and the Higgs vacuum expectation value, and applies the findings to a specific SU(6) model, assessing the quality of unification.
