GUT Precursors and Non-Trivial Fixed Points in Higher-Dimensional Gauge Theories

TL;DR

This paper explores the possibility of observing GUT precursor states at lower energies in higher-dimensional gauge theories, proposing new ways to probe grand unification physics at accessible scales.

Contribution

It introduces the concept of GUT precursors and demonstrates the feasibility of detecting them at TeV scales within higher-dimensional models.

Findings

GUT states like X and Y gauge bosons can appear at TeV scales.

Hybrid models with separated energy scales are theoretically consistent.

Higher-dimensional theories can realize non-trivial fixed points and be deconstructed.

Abstract

Within the context of traditional logarithmic grand unification at M_GUT = 10^(16) GeV, we show that it is nevertheless possible to observe certain GUT states such as X and Y gauge bosons at lower scales, perhaps even in the TeV range. We refer to such states as ``GUT precursors.'' Such states offer an interesting alternative possibility for new physics at the TeV scale, even when the scale of gauge coupling unification remains high, and suggest that it may be possible to probe GUT physics directly even within the context of high-scale gauge coupling unification. More generally, our results also suggest that it is possible to construct self-consistent ``hybrid'' models containing widely separated energy scales, and give rise to a Kaluza-Klein realization of non-trivial fixed points in higher-dimensional gauge theories. We also discuss how such theories may be deconstructed at high energies.
