[en] Families of vector mesons Ρ,Ψ,Υ, contain an infinite number of resonances with gradually increasing widths are considered. The asymptotic freedom requirement involves a relationship between the electric width of k-th resonance and its mass M_k derivative over the number k. It is shown that for the families of Ψ and Υ mesons the moment from experimental function R(s) is equal to the sum of the moment from a bare quark loop and the edge term which stems from replacing of summation by integration. These equalities are fulfilled up to 1% for 60 moments in the Ψ-meson family and up to 2% for 96 moments in the Υ-meson family. The electronic widths of the resonances and the Ρ-meson mass are calculated. 7 refs

[en] The value of gluonic condensate is calculated using the supposed earlier QCD model with infinite number of vector mesons. For polarization operator connected with the vector current of c-quarks Π^c(Q²) within the interval O< Q²<∞ the Wilson operator expansion is used. In the operator expansion only the unit operator and the operator connected with gluonic condensate are remained. The electronic widths of the ground and excited states of ρ, Ψ, γ-meson families are calculated. 12 refs.; 2 figs.; 1 tab

[en] The contribution to the α_μ(hadr) muon anomalous magnetic moment vacuum polarization and to the electromagnetic bond constant α(q²) by the q² = M_z² is verified in connection with the new more exact value of the ρ-meson electron width. The QCD model with the infinite number of the vector mesons was applied. The values α_μ(hadr) = 678(7) x 10^-10, δα_hadr(M_z²) = 0.02786(6)

[en] The microcausality requirements for neutrino scattering by a nucleon are studied. Analitical behaviour in both complex variables v and q² of the forward elastic scattering amplitudes Tsub(i)(v, q²) of a virtual vector meson with its mass q² is obtained. The formulas are derived expressing the amplitudes Tsub(i)(v, q²) for arbitary complex v and q² through the functions Wsub(i)(v, q²) which describe neutrino scattering by the nucleon. The validity of the spectral representation for the functions Wsub(i)(v, q²) is proved. The spectral functions hsub(i)(a, α) of this representation are written in terms of the values of the functions Wsub(i)(v, q²) in the vp-scattering physical channel

[en] The restrictions on the pion electromagnetic form factor F_π(Q²) and on its contribution to the muon anomalous magnetic moment α_μ^F following from the analytical properties of the form factor and its experimental values measured at 45 points Q_k² (k = 1, ..., 45) in the space-like region are investigated

[en] Sum rules are proposed which enable one to calculate the electronic widths of excited states of vector mesons belonging to PSI-, EPSILON- and rho-meson families, provided their masses are known. The calculated values of the electronic widths are in agreement with the experiment

[en] The value of the gluon condensate is calculated making use of the QCD model with infinite number of vector mesons. The corersponding polarization operators Π(Q²) and Π(Q²) are required to be close to the Wilson operator expansion. This requirement is used to obtain the values 0.04<(α_s/π)G²<0.12 GeV⁴ from the analysis of the ψ-meson family and Z) 0.05<(α_sπ)G²<0.1 GeV⁴ from analysis of the Γ-meson family. The electron widths of the mesons under consideration are calculated

[en] The radiative decay D(1285)→Φγ is studied in a potential model. A term which explicitly violates the Okubo-Zweig-Inzuki rule is introduced into potential model, the value of the term being chosen so as to explain the observed decay width. The value of the mixing angle α∼-25 deg is found from the potential model calculations and from the masured widths of the decays D→Φγ, D→γγ^*, and E(1420)→γγ^*. The widths of decays D→ωγ, E→ωγ, and E→Φγ are calculated
