Holographic Stability For Non-Qq Candidates

In the context of bottom-up AdS/QCD models, we discuss how the configurational entropy can describe heavy non-qq¯ states. Using the nonquadratic softwall model, introduced to describe nonlinear Regge trajectories, we parametrize different multiquark and exotic meson structures to describe Zc, ψ, and Zb states as non-qq¯ hadrons in terms of stability. We found that Zc is better described as a hybrid meson with one gluon tube, ψ as hadrocharmonium, and Zb as hadronic molecule.
