Amplitude Analysis in Hadron Spectroscopy

Vincent Mathieu (Indiana University, Bloomington)

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. Photoproduction of a non-strange meson in the energy range accessible at
the ELSA and MAMI experiments is also discussed.  I review the theoretical issues for these reactions and possible methods to solve them.
