Properties of Holographic Mesons on Dense Medium

TL;DR

This paper investigates how holographic light mesons behave in dense nuclear media, revealing how their energy and decay constants vary with momentum and isospin charge, influenced by background chemical potentials.

Contribution

It provides a detailed analysis of meson dispersion relations and decay constants in dense media using holographic models, highlighting isospin-dependent effects.

Findings

Meson energy dispersions increase with momentum and split by isospin charge.

Decay constants differ between positive and negative mesons due to chemical potentials.

Negative mesons have larger decay constants than positive ones of the same type.

Abstract

We study the energy dispersions of holographic light mesons and their decay constants on dense nuclear medium. As the spatial momenta of mesons along the boundary direction increase, both observables of the mesons not only increase but also split according to the isospin charges. The decay constant of the negative meson is more large than that of the positive meson of the same type due to the chemical potentials of the background nucleons.
