QCD Dual

TL;DR

This paper proposes a new QCD dual solution satisfying anomaly matching, predicting the critical flavor number for infrared fixed points, aligning with nonperturbative bounds from the all-orders beta function.

Contribution

It introduces a novel dual gauge theory solution that matches anomalies and predicts critical flavor thresholds consistent with nonperturbative bounds.

Findings

Predicts the critical number of flavors for IR fixed points in QCD.

Aligns the dual theory's predictions with nonperturbative bounds.

Provides a new perspective on QCD phase structure.

Abstract

We uncover a novel solution of the 't Hooft anomaly matching conditions for QCD. Interestingly in the perturbative regime the new gauge theory, if interpreted as a possible QCD dual, predicts the critical number of flavors above which QCD in the nonperturbative regime, develops an infrared stable fixed point. Remarkably this value is identical to the maximum bound predicted in the nonpertubative regime via the all-orders conjectured beta function for nonsupersymmetric gauge theories.
