Summary of the most significant results reported in this session

In the following a summary is presented of five parallel sessions on light quark had- ron spectroscopy. In general all topics which were discussed in the plenary sessions, and for which the proceedings contain separate (invited) papers, will be left out; only occa- sionally (and for reasons of completeness) will we make a reference to these presentations. Several other restrictions can be made. Nearly all papers submitted to the (parallel) hadron spectroscopy sessions were experimenta1 1 ), the only exceptions being a series of four theoretical papers on the baryonium problem. Furthermore, there was virtually no new information concerning the 'classical' baryons. In particular, no new facts were submitted on the problem of the possible existence of baryon states outside the so-called minimal spectrum, i.e. outside {56,L+ } and {70,L-dd}, the existence of the {ZO}'s, and the exis- even o tence of (baryon) exotic states. There was one contribution on a 'possible' new:".* 2 ), and a report on the final measurement of the L:+ magnetic moment with the HYBUC bubble chamber 3 ). Recent work on 1TN phase-shift analysis was presented in the plenary sessions•). The re- maining baryon contributions were on searches for narrow states. As a result of the situation described above, this summary will to a large extent deal with meson spectroscopy only, both with the conventional mesons ( qq - see Section 1) and with the narrow and broad mesons coupled mainly to BB (see Section 2). In (a short) Section 3 we will mention the results of the narrow baryon searches. For the qq mesons the data ob- tained will be discussed in the framework of simple SU(6). For the other topics a more 'emunerative' approach will be necessary.
