Quantization rules in holographic QCD models

<jats:p>In this paper, we investigate quasinormal modes in holographic QCD models from the perspective of the WKB approximation. We derive the generalized Bohr-Sommerfeld quantization rules for quasistationary states in holographic QCD models. As a simple application of these formulas, we compute the quasinormal modes of scalar and vector fields in the soft-wall model, where an analytic expression for the real part of the frequency can be found in the low-temperature regime. Additionally, this study provides useful insights into the dissociation process in holographic QCD models.</jats:p>
