Remarks on Heavy-Light Mesons from AdS/CFT

TL;DR

This paper uses the AdS/CFT correspondence to analyze the energy spectrum of heavy-light mesons in a supersymmetric gauge theory, revealing that excitation energies are independent of heavy quark mass, akin to QCD.

Contribution

It provides a novel holographic computation of heavy-light meson spectra in a supersymmetric setting, highlighting mass independence of excitations.

Findings

Excitation energies are independent of heavy quark mass.

Results are consistent with QCD-like behavior.

Remarks on models with less supersymmetry are included.

Abstract

We use the AdS/CFT correspondence to compute the energy spectrum of heavy-light mesons in a N=2 SU(N) super Yang-Mills theory with two massive hypermultiplets. In the heavy quark limit, similar to QCD, we find that the excitation energies are independent of the heavy quark mass. We also make some remarks about related AdS/CFT models of flavor with less supersymmetry.
