Deformed AdS/QCD, mesonic mass spectra, and DCE: Still a margin for heavier resonances

TL;DR

This paper employs a deformed AdS/QCD soft-wall model combined with differential configurational entropy to estimate heavier meson resonances, potentially identifying candidates omitted from current experimental data.

Contribution

It introduces a novel approach merging AdS/QCD and DCE to predict higher mesonic resonances beyond existing experimental data.

Findings

Estimated masses for heavier meson resonances beyond PDG data.

Identification of potential new meson candidates.

Validation of the model through Regge-like trajectories.

Abstract

The mass spectra of light-flavor mesons are analyzed in a deformed AdS/QCD soft-wall model, driven by four distinct anomalous 5-dimensional mass corrections of the scalar field, coupled to Einstein--Hilbert gravity, from the QCD running coupling. Using the differential configurational entropy (DCE) underlying the families of pseudoscalar, axial-vector, scalar, and vector mesons, the mass spectra of heavier meson resonances with radial quantum numbers beyond the ones already in the summary table of Particle Data Group (PDG) are then estimated. This protocol merges AdS/QCD and experimental data in PDG through Regge-like trajectories. Some of the estimated meson resonances may be identified as further candidates omitted from the summary table in PDG.
