SUMMARY:

Configurational information measures have proven to be effective tools for extracting data from various physical systems using quantities such as entropy and complexity. When used in conjunction with AdS/QCD models, especially in hadron spectroscopy, these tools can identify properties of advanced particle states, allowing them to be recognized as possible counterparts of experimentally detected and cataloged particles that have not yet been identified. In this work, configurational information measures are applied to an AdS/QCD model with a deformed dilaton, so that the constituent mass of quarks could be taken into account. With this modification, the properties of particles composed of slightly heavier quarks can be analyzed with greater precision. This is the case for kaons, mesons with a strange quark in their composition, which are our main object of study. Differential configurational entropy and differential configurational complexity were computed for the family of strange vector kaons,
obtaining the mass spectra as a function of their resonance states. As a consequence of the modified dilaton, the Regge trajectories for the kaons become nonlinear, differing from the usual observations in light meson spectroscopy, but accurately reproducing the obtained masses.  From the expressions obtained that interpolate the results and using both entropy and complexity as intermediaries, the mass spectra was extrapolated to higher resonance levels, and the obtained states found possible counterparts among unidentified particles in the Particle Data Group.
