AbstractAbstract
[en] The properties of the G(1590) meson recently discovered at the Institute of High Energy Physics are analyzed by using a model based on the assumption that the interaction between hadrons is carried by their confined components (by the virton spinor and vector fields). The available experimental data support the assertion that the G(1590) meson is a scalar gluonium

AbstractAbstract
[en] Twenty years ago, the Particle Data Group adopted a systematic naming convention for baryons: the symbols N, Δ, Λ, Σ, Ψ, and Ω were to identify the isospin and strangeness, The mesons, by contrast, have become an alphabet soup of uninformative names - theta, iota, xi, zeta, g/sub T/, g/sub s/, H, E, delta, h, g, r, kappa, etc. -, and in some cases identical names are used for mesons with different quantum numbers (A, B, and D). Furthermore, experimentalists are now discovering baryons that contain heavy quarks. It is therefore timely to consider systematic naming conventions both for mesons and for baryons with heavy quarks. The Particle Data Group is circulating this proposal in the hope of generating feedback, and we attach a sheet for responses. It should be emphasized that the Particle Tables would show both the old and new names for some time

AbstractAbstract
[en] We present experimental evidence for the existence of the decay psi (3684) →γ,chi, chi→4π/sup plus-or-minus/, 6π/sup plus-or-minus/, π+π-K+K-, π+π-, and K+K-. There is clear evidence for at least two chi states, one at 3.41plus-or-minus0.001 GeV/c2 and the other at 3.53plus-or-minus0.02 GeV/c2. The chi (3410) decays into ππ and KK and thus must have even spin and parity

AbstractAbstract
[en] Coupling schemes are considered for multiquark mesons, specifically those connecting the diquark--antidiquark (antiQ2Q2) mesons to conventional mesons and baryons. The resulting unique scheme is given, where the wave function is the three-quark composite baryon tensor having given properties. 6 references

AbstractAbstract
[en] Constraints on quark diagrams for exclusive decays from group theory are investigated. In contrast to previous statements, we find a one-to-one correspondence between reduced matrix elements of flavor symmetry (SU3) and the ''naive'' quark diagrams of the spectator and annihilation type. In Cabibbo suppressed decays however, group theory relates penguin and annihilation (W-exchange) diagrams, consequently ruling out models with spectator dominance and large penguins. These results are expected to be more general, having as yet been illustrated for two-body decays of charmed mesons
