[en] In the 13th Moriond meeting, special emphasis has been put on the phenomenology of quantum electrodynamics, especially on lepton pair production, gluon physics and multiquark states. 38 papers are given in the first volume of the proceedings

[en] An amplitude analysis of the reaction anti-pp → π-π+ between 2.0 and 2.6 GeV has revealed resonances with Jsup(PC)/Isup(G) =3--1+, 4++0+, 5--1+ and widths approximately equal to 150-200MeV. The differential cross section zeros of anti-pp → K-K+ confirm these results and provide evidence for new states with Jsup(P) = 3-, 5- with I=0, at masses close to those of the I=1 states. (author)

[en] The possible role of gluons in hadronic processes as suggested by the quark-parton model and QCD is discussed and evaluated. Attention is focused on heavy (e.g., charmed) hadron production, large P sub (T) hadronic physics, and massive lepton pair production at large P sub (T). A discussion of more rigorous tests of QCD and the role of gluons in e+e- annihilation is also given

[en] Unconventional hadrons are reviewed. The two quark-two antiquark states which are expected to be prominent in the low energy meson-meson S-wave and in baryon antibaryon annihilation are discussed in detail. (author)

[en] Ways are discussed in which gluons can be studied experimentally, with emphasis on non-perturbative methods. Some possibilities are hadron multiplicities, central region particle ratios, sigma sub(T) gluon resonances. It is argued that quark jets and gluon jets will behave qualitatively differently.

[en] It has been proposed that, in addition to the conventional P wave q anti-q nonet of 0++ mesons, there should be a second 0++ nonet composed of qq anti-q anti-q states nearby in mass. This nonet contains the lightest multiquark states and is therefore particularly suitable for experimental investigation. The status of 0++ mesons in the light of this proposal is reviewed. (authors)

[en] A brief review of the general properties of the nucleon-antinucleon interaction and their relationships with better known hadronic processes is given. Difficulties connected with the large annihilation cross section and the existence of narrow resonances are discussed and a possible remedy proposed. (author)
