摘要：

We discuss some of the most relevant non-standard quark configurations in hadron spectroscopy, which are alternative to the qqq and q ($) over bar description of baryons and mesons, respectively. They include the quark-diquark and four-quark (five-quark) meson-meson (meson-baryon) bound states. To this purpose, we briefly review the diquark model of baryons and tetraquark states and the hadro-quarkonium model of heavy-light tetra- and pentaquarks. Some applications of the previous models are discussed.
