This work uses the connection between hadronic stability and configurational entropy to explore hadronic structures written in terms of non-quadratic dilaton (κ z)2-α. These hadronic structures are described using the relation between the parameters κ and α with the constituent mass. We test Zc, Zb, and ψ as non-qq states defined as hybrid meson, hadroquarkonium, hadronic molecule, or diquark-antidiquark pair. We find that, holographically speaking, Zc and ZB are better described as a hybrid meson and ψ as hadrocharmonium.
