==============================================================================
The Workshop "N* Physics and non-perturbative QCD" will be held at the
European Centre for Theoretical Physics and Related Areas (ECT*) in Trento
(Italy) from May 18 to May 29, 1998. It is a joint initiative of the ECT* and
the Jefferson Laboratory at Newport News (USA), sponsored by the ECT* and
partially supported by the JLAB and the CEA-Saclay, and it is the continuation
of a series of workshops held in the past few years, starting at the Florida
State University in 1994 and continuing at CEBAF in 1995, at the Institute
for Nuclear Theory of Seattle in 1996 and at the George Washington University
in 1997.
The Workshop is devoted to a summary of recent experimental and theoretical
research on the N* physics and it is aimed at developing close collaborations
among experimentalists and theoreticians in order to pursue the intepretation
of the huge aumont of forthcoming data from several laboratories in the world.
In particular, the Workshop will focus on the information that the photo- and
electro-production of nucleon resonances can provide on the non-perturbative
regime of QCD.
==============================================================================
FORMAT OF THE WORKSHOP
==============================================================================
The format of the Workshop is based both on topical lectures (generally two
in the mornings and one in the afternoons) and shorter contributions. In the
afternoons informal discussion meetings, with a discussion leader, are also
planned.
