PRESENTATION OF THE HADRON SPECTROSCOPY PARALLEL SESSIONS

Abstract
At this Conference, four parallel sessions have been devoted to Hadron Spectroscopy. As a matter of fact, the limits of this topic are not well defined. Clearly the baryon and meson resonances results obtained in formation and production experiments constitute a part of Hadron Spectroscopy ; furthermore it seems reasonable that the meson or baryon diffractive enhancements which are more and more believed now to be non resonant should also be discussed in this session. However it is almost impossible to separate the study of the nature and spin parity properties of these objects from the study of their production mechanism ; a large overlap is therefore unavoidable with the session 8 where these mechanisms are discussed. In the same way, the mini-rapport of Dr. Faiman (session 6), where the new theoretical idea concerning the baryon classification are presented is obviously strongly connected with Hadron Spectroscopy. Finally, I would like to apologize for the numerous interesting theoretical papers (papers n° 211, 322, 323, 32, 89, 233, 234, 373) which also deal with this session and have not been reported therein by lack of space, and I suggest that the specialists consult them directly.
