Vector Meson Spectrum from top-down Holographic QCD

TL;DR

This paper derives a holographic model of QCD that predicts the vector meson spectrum, showing how specific parameter choices can match experimental data, bridging gauge theory and gravity.

Contribution

It presents a top-down holographic approach to compute the vector meson spectrum in a QCD-like theory, with parameter tuning for empirical accuracy.

Findings

Vector meson spectrum obtained from holographic model.

Parameter choices can match experimental data.

The model describes confinement and scale invariance transitions.

Abstract

We elaborate on the brane configuration that gives rise to a QCD-like gauge theory that confines at low energies and becomes scale invariant at the highest energies. In the limit where the rank of the gauge group is large, a gravitational description emerges. For the confined phase, we obtain a vector meson spectrum and demonstrate how certain choice of parameters can lead to quantitative agreement with empirical data.
