TL;DR

This paper explores a non-supersymmetric quiver gauge theory derived from AdS/CFT correspondence, proposing a unification scale around 4 TeV with potential implications for particle physics beyond the Standard Model.

Contribution

It introduces a novel non-supersymmetric quiver gauge theory framework based on orbifolding, predicting unification at approximately 4 TeV, and discusses its robustness and experimental implications.

Findings

Unification scale estimated at about 4 TeV.

Proposes a specific orbifold structure with p=12 and N=3.

Discusses compatibility with precision electroweak measurements.

Abstract

The use of the AdS/CFT correspondence to arrive at quiver gauge field theories is dicussed, focusing on the orbifolded case without supersymmetry. An abelian orbifold with the finite group $Z_{p}$ can give rise to a $G = SU(N)^p$ gauge group with chiral fermions and complex scalars in different bi-fundamental representations of $G$. The precision measurements at the $Z$ resonance suggest the values $p = 12$ and $N = 3$, and a unifications scale $M_U \sim 4$ TeV.The robustness and predictivity of such grand unification is discussed.
