Amplitude Analysis in Hadron Spectroscopy
Vincent Mathieu (ECT* Trento)

There are several experiments in Europe (COMPASS, LHCb), USA (CLAS, GlueX) and Asia (BES, Belle) devoted to hadron spectroscopy. In this talk, their goals and prospects are presented with a special emphasis on the discovery of new ‘exotic’ resonances.
There are indeed indications from these experiments about resonances (hybrid mesons, glueballs, tetraquarks, etc) beyond the quark model classification. However a close collaboration between theorists and experimentalists is necessary to draw robust conclusions about their existence. I review the theoretical developments necessary to fully exploit the data provided by the experiments and finally reach their objectives.
