[en] We discuss the compatibility of the naive Pomeron [αp(0) = 1] for the parton amplitudes with the absence of physical singularities in the colored channels (confinement)

[en] The mass of the axial charmed meson is calculated within the method of QCD sum rules

[en] The work reported in the present article was undertaken to search for fragment activity of short-lived products of the interaction of electrons of energy 1200 and 700 MeV with bismuth nuclei. Delayed fission was observed at electron energy 1200 MeV. This is explained as arising from the fission of heavy hypernuclei

[en] The radiative corrections to the cross section for single-photon e⁺e^- annihilation at high energies which are associated with the initial electron and positron are calculated with accuracy 0.1% for the interval of energies 0.2<2E<10 GeV in the c.m.s. of the beams. The cross section for single-photon annihilation with inclusion of radiative corrections is represented in the form of the cross section for the Drell--Yan process. Various experimental schemes are considered. A critical review is given of previously published formulas for the cross section with inclusion of radiative corrections

[en] Within the framework of the optical model, experimental data on cross sections and polarization for elastic proton scattering by ⁵¹V nuclei at energies E/sub p/< or approx. =10 MeV are analyzed. The parameters of the optical potential (OP) are found which reproduce satisfactorily the experimental differential cross sections for elastic scattering, the polarization, and the energy dependence of the total cross section. The usefulness of the sets of the OP parameters proposed earlier for description of these functions is tested. The energy dependence of the cross section for elastic proton scattering through the compound nucleus (sigma/sub C/E) for ⁵¹V, the energy dependence of the total cross section, and the dependence of the value of the three-dimensional integral of the imaginary potential per nucleon on the energy of incident protons in a broad energy range are investigated

[en] We propose a quantum statistical description of nuclear systems with a prominent global dynamics and strong coupling to the internal degrees of freedom (the double nuclear system in heavy-ion reactions or the parent nucleus during the descent in fission). It is shown that there exists a regime in which an adiabatic perturbation theory can be developed. The basic kinetic equation is constructed taking into account correlations between the global motion and internal transitions. The main features of the equation and the relation to the traditional approaches are discussed

[en] On the basis of analysis of experimental data on CC collisions at momentum 4.2 GeV/c per nucleon we verify the picture of the interaction of relativistic nuclei based on a nuclear pionization model. We show that processes occurring in nucleus-nucleus collisions have a collective nature. The experimental data are consistent with the idea of a partial separation of the nucleonic and mesonic components of the interaction products of relativistic nuclei and a thermodynamic form of the secondary-particle spectrum

[en] The origin of the radiation in the energy range 10¹⁵--10¹⁶ eV detected in the direction of the galactic source Cygnus X-3 is discussed. There are difficulties in the interpretation of this radiation as γ rays. We consider the possible role of neutrinos nu-bar/sub e/ and photinos in this phenomenon. The fluxes of photinos due to gluino decay in the source are calculated. The cross sections for photino scattering on nucleons and electrons are calculated and the generation of extensive air showers (EAS) in the Earth's atmosphere is discussed. It is shown that neutrinos are very efficient at generating EAS owing to the resonance scattering reaction nu-bar/sub e/+e^- → W^- → hadrons. However, our calculations exclude both of these possible explanations of the Cygnus X-3 radiation since they require too large a source luminosity

[en] Decays of bound states of light scalar quarks are studied. The partial widths ( rho/sub s/→π/sub s/γ, π/sub s/→γγ, π/sub s/→hadrons) of scalar-containing hadrons with the quantum numbers J /sup P//sup C/ = 1^--( rho/sub s/) and 0⁺⁺(π/sub s/) are found

[en] Elastic α-particle scattering by nuclei with nonzero spin is considered in the approximation in which, besides the elastic potential-scattering channel, one inelastic exchange channel, namely, the channel corresponding to the disintegration of the target nucleus into two fragments, is open. The amplitude of the exchange processes is computed within the framework of a consistent finite-range distorted-wave method. It is shown in the particular case of elastic α-particle scattering by lithium nuclei that the inclusion of the exchange correction to the scattering amplitude and the consideration of the spin--orbit interaction between the impinging particle and the target nucleus improve the agreement with experiment
