TL;DR

This paper investigates how mesons in a holographic quark-gluon plasma respond to finite temperature and chemical potential, focusing on excitation times and stability effects.

Contribution

It introduces a study of meson excitation dynamics at finite chemical potential and temperature using holographic models, highlighting the dependence on stability and plasma parameters.

Findings

Excitation time increases with higher temperature and chemical potential.

More stable mesons are excited more quickly.

Meson stability influences excitation dynamics.

Abstract

We consider a probe stable meson in the holographic quark-gluon plasma at zero temperature and chemical potential. Due to the energy injection into the plasma, the temperature and chemical potential are increased to arbitrary finite values and the meson is also excited. Excitation time tex is the time at which the meson falls into the final excited state. We study the effect of various parameters of theory on the excitation time and observe that for larger values of final temperature and chemical potential the excitation time increases. Furthermore, our outcomes show that the more stable mesons are excited sooner.
