Gauge coupling unification in gauge–Higgs grand unification

摘要

We discuss renormalization group equations for gauge coupling constants in gauge–Higgs grand unification on five-dimensional Randall–Sundrum warped space. We show that all four-dimensional Standard Model gauge coupling constants are asymptotically free and are effectively unified in $ extit {SO}(11)$ gauge–Higgs grand unified theories on 5D Randall–Sundrum warped space.
