The no-wall holographic model for vector quarkonia

TL;DR

This paper introduces a no-wall holographic model that describes vector mesons with various quark masses, predicting their spectral properties in line with experimental data and theoretical expectations.

Contribution

It develops a universal no-wall holographic framework for vector mesons that accounts for arbitrary quark masses, extending previous models.

Findings

Model predicts radial Regge trajectory parameters depend on quark masses.

Results agree with meson phenomenology.

Provides a theoretical basis for vector meson spectra.

Abstract

We use the no-wall holographic approach (a relative of the soft-wall one) to construct a universal description of vector mesons with arbitrary quark masses. The proposed model predicts a specific dependence of the parameters of radial Regge trajectories on the quark masses in a reasonable agreement with the meson phenomenology and some theoretical expectations.
