Three quark and quark–diquark models are characterized by several missing resonances, even if in the latter case the state space is a reduced one. Moreover, even quark–diquark models show some differences in their predictions for missing states.

We discuss some of the most relevant non-standard quark configurations in hadron spectroscopy, which are alternative to the qqq and $$q \bar{q}$$ description of baryons and mesons, respectively. They include the quark-diquark and four-quark (five-qua

We describe the relativistic interacting quark-diquark model formalism and its application to the calculation of strange and nonstrange baryon spectra. The results are compared to the existing experimental data. We also discuss the application of the

The formalism for a new generation of unquenched quark models for baryons in which the effects of quark–antiquark pairs are taken into account in an explicit form via a microscopic, QCD-inspired, quark–antiquark creation mechanism, is presented.
