Abstract

Hadron spectroscopy represented in the past a major tool for understanding the fundamental symmetries of strong forces. More recently, the interest on this topic has been revitalized by the discovery of new quarkonium-like resonances, that do not fit in the standard picture and whose understanding could improve our mastery of quantum chromodynamics. I review here the experimental signatures of these exotic hadrons, at present and future e+e- and hadron collider experiments.
