AdS/CFT Inspired String Phenomenology

TL;DR

This paper explores how AdS/CFT correspondence can be used to construct quiver gauge theories without supersymmetry, potentially leading to new grand unification models at TeV scales.

Contribution

It introduces a framework for deriving non-supersymmetric quiver gauge theories from orbifolds, with specific predictions for gauge groups and unification scales.

Findings

Finite group orbifolds can produce gauge groups with chiral fermions.

Predicted unification scale around 4 TeV.

Model consistent with precision measurements at Z resonance.

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.
