Description

This work uses the connection between hadronic stability and configurational entropy to explore hadronic structures written in terms of nonquadratic dilaton $(\kappa z{)}^{2-\alpha }$. These hadronic structures are described using the relation between the parameters $\kappa$ and $\alpha$ with the constituent mass. We test $Z_c$ and $\psi$ as non $q\overline{q}$ states defined as hadroquarkonium, hadronic molecule, or diquark-antidiquark pair. We find that photographically speaking, $Z_c$ is better described as a hybrid meson and $\psi$ as hadrocharmonium.
