[en] This paper reviews some of the very exciting work on resonances in the past year following the discovery of the J/psi. A number of important few-body aspects are pointed out. Work presented on generalized isobar models used to do resonance analysis are pointed out. The important question of whether the A₁ is a true resonance is the focal point of this discussion. Relevant new experiments and dynamical calculations lend support to the existence of the A₁. Papers concerning the ΔΔ content of the deuteron are also summarized. This seems to be a difficult question to answer quantitatively. The many new developments in high energy spectroscopy starting with the remarkable simultaneous discovery of the very narrow meson resonance at 3.1 GeV at Brookhaven (the J) and at SLAC, (the psi (3,1)) are reviewed. Most of the phenomena can be explained by the assumption of a new heavy c quark (possibly the charmed quark predicted by Glashow). Some problems in which few body systems play an important role are singled out. (Auth.)

[en] The glow model of broken QCD allows for free, low-mass, fractionally charged, glow-singlet, color 6, diquarks Q. Although these composite Q's may be difficult to produce at present e⁺e^- and hadronic energies, the situation could be much more favorable in heavy-ion collisions. In contrast to other models, the glow model allows for parameters which could lead to the production of fractional charge at Bevalac energies. A two stage experiment is in progress: The first step consisted of an (initial) exposure of a heavy target configuration to a total of 3 x 10¹⁰ Fe ions of 1.9 GeV/nucleon kinetic energy. Fractional charge which escaped the target was stopped in five gallon tanks of CCl₄ and collected (and thus concentrated) on thin central wires. The target materials and collection wires were distributed to a number of laboratories conducting experiments designed to look for free fractional charge in bulk matter. The first results from the SFSU automated Millikan droplet experiment found less than one fractional charge produced per 10⁴ Fe-Pb collisions (and with further assumptions, less than one for 2 x 10⁶ collisions). 14 references

[en] The tests and constraints of composite models for fermions are reviewed. Possible indications for composite fermions are listed: families, excitations, actual constituents, moments and transitions, complicated-effective forces, form factors, high spin, and 't Hooft's conditions. A relativistic calculation of a pointlike composite fermion is reviewed. The SO₁₄ unified composite model is examined in light of the enormous difficulty seen in obtaining a full dynamic calculation for a composite electron as constrained by equation 4. The limits of F₂ for quarks from e+e- annihilation are also investigated
