Abstract

Even-spin glueball resonances in AdS/QCD are here studied using the configurational entropy (CE). The concept of CE Regge trajectories, associating the CE of the even-spin glueball resonances with both their spin and to their mass spectra, is used to derive the mass spectra of higher resonances with J even. For it, the linear, the exponential modified, and the anomalous quadratic dilatonic models, each one with linear and logarithmic anomalous corrections, are employed. Several methods are implemented, hybridizing AdS/QCD and established data of lattice QCD.
