Description
Higher-dimensional gauge theories provide a compelling framework for physics beyond the Standard Model, offering new approaches to gauge unification and ultraviolet (UV) completions. In particular, five dimensional (5D) theories compactified on orbifolds can generate realistic four dimensional (4D) models through boundary conditions, while asymptotically safe dynamics may render them UV complete.
We investigate the theoretical viability of such constructions from several complementary perspectives. We will review the role of orbifold compactification and the conditions required for the resulting setup to remain consistent and stable, as well as the renormalization properties of 5D gauge theories. We then illustrate these general considerations through a concrete 5D SU(6) model. After constructing the theory and its symmetry-breaking structure, we perform a set of consistency checks and examine how the model fits within the broader framework of viable higher-dimensional unified theories.
