Studying the internal structure of exotic hadrons and bound states using spectroscopy and complementary techniques with ALICE

The internal structure of hadrons, bound states, and the existence of excited states can be studied using hadron spectroscopy. Complementary information can be obtained using the multi-particle correlation technique, from which it is possible to infer the existence and properties of bound states, and by measuring the hadron yields and comparing them with predictions of the statistical hadronization model. The latter has proved to be a powerful tool to calculate hadron abundances and allows us to deduce indirectly the number of excited states of a given hadron species, including weakly bound states such as hypernuclei. These proceedings describe recent results on short-lived exotic resonance production, hypernuclei structure, and searches for exotic bound states in different collision systems. The implications of these results on the hadron structure and possible excited states are also discussed.
