Isospectrality and configurational entropy as testing tools for bottom-up AdS/QCD

Abstract

This work discusses the connection between isospectrality and configurational entropy in holographic bottom-up models. We analyze the effect of monoparametric isospectral transformation in holographic decay constants and configurational entropy for a set of softwall-like models at zero temperature. We conclude that the isospectral parameter λ defines a window of possible holographic models suitable for describing spectroscopy.
