  • Tikhomirov, V.V.; Sytov, A.I. (Вопросы атомной науки и техники, 2012)
    The paper concerns the future LHC crystal based collimation system. The dependence of collimation efficiency on the muscut angle characterizing nonparallelity of the channeling planes and crystal surface is mainly addressed. ...
  • Vlasii, N.D. (Вопросы атомной науки и техники, 2012)
    The long-standing problem of a divergent behaviour of the Aharonov-Bohm scattering amplitude in the forward direction is reconsidered. We show that this divergence has no physical consequences, being an artefact of the ...
  • Gakh, G.I.; Konchatnij, M.I.; Levandovsky, I.S.; Merenkov, N.P. (Вопросы атомной науки и техники, 2012)
    Two possibilities of the measuring high-energy photon circular polarization by means of the process γ + e⁻ → e⁺ + e⁻ + e⁻ are investigated. The first one is connected with the measurement of polarization asymmetry of the ...
  • Novak, O.P.; Kholodov, R.I. (Вопросы атомной науки и техники, 2012)
    Resonant e⁺e⁻–-pair production by an electron in a magnetic field near the process threshold is analytically studied. Using the Nikishov's theorem we estimate the number of events in the magnetic field equivalent to laser ...
  • Bondarenco, M.V. (Вопросы атомной науки и техники, 2012)
    It is argued that W/Z boson production in ultra-relativistic pp collisions in the fragmentation region, subject to a kinematic cut on the boson transverse momentum Q┴ > Q┴min, with 1 GeV/c << Q┴min, << MW/Z, must be dominated ...
  • Fomin, P.I.; Kholodov, R.I. (Вопросы атомной науки и техники, 2012)
    Theoretical investigations of quantum electrodynamic processes in strong magnetic field are carried out. Such the processes may occur between colliding heavy ions. Magnetic fields of the nuclei are added and electric fields ...
  • Anchishkin, D.V.; Muskeyev, A.O.; Vovchenko, V.Yu.; Yezhov, S.N. (Вопросы атомной науки и техники, 2012)
    Evolution of the hadronic system in heavy-ion collisions is studied with the reaction density. The three-dimensional reaction zones and their projections for different types of hadronic reactions are calculated for AGS and ...
  • Sitenko, Yu.A.; Vlasii, N.D. (Вопросы атомной науки и техники, 2012)
    Quantum-mechanical scattering of coherent high-energy charged particles by a magnetic vortex is considered. The vortex core is assumed to be impermeable to scattered particles, and effects of its transverse size are taken ...
  • Flanchik, A.B.; Kontorovich, V.M. (Вопросы атомной науки и техники, 2012)
    A gamma radiation from pulsars due to inverse Compton scattering of coherent low-frequency radiation on relativistic electrons in a polar gap have been considered. The radio emission in the gap arises due to sub relativistic ...
  • Shatnev, M.G. (Вопросы атомной науки и техники, 2012)
    Radiation emitted from high-energy planar channeled positrons in crystal is studied in the framework of quantum electrodynamics to calculate the polarization characteristics of this radiation. Under our approach the general ...
  • Shul'ga, N.F.; Trofymenko, S.V.; Syshchenko, V.V. (Вопросы атомной науки и техники, 2012)
    The problem of measurement of bremsstrahlung characteristics in the process of sharp scattering of relativistic electron in the case when transverse distances responsible for radiation process have macroscopic size is ...
  • Cirilo-Lombardo, Diego Julio (Вопросы атомной науки и техники, 2012)
    Unified field theoretical models based on generalized affine geometries are proposed, described and analyzed from the physical and mathematical points of view. The relation between torsion and spin of the models is explicitly ...
  • Elizalde, E.; Skalozub, V. (Вопросы атомной науки и техники, 2012)
    It is assumed that the intergalactic magnetic fields were spontaneously generated in the early Universe due to vacuum polarization of non-Abelian gauge fields at high temperature T. Here, a procedure to estimate the field ...
  • Jenkovszky, László; Nagy, István (Вопросы атомной науки и техники, 2012)
    After a brief historical overview, we present recent results on high-energy diffraction, elastic and inelastic, with emphasis and comments on the recent experimental results from the Large Hadron Collider (LHC) at CERN.
  • Starodub, S.S.; Roshchupkin, S.P. (Вопросы атомной науки и техники, 2012)
    It is a model theoretical work of the applied character in which: outside the framework of the dipole approximation (with an accuracy of about v/c) the effective interaction force between two atoms of hydrogen at their ...
  • Korchin, A.Yu.; Kovalchuk, V.A.; Lazarenko, D.O. (Вопросы атомной науки и техники, 2012)
    The fully differential angular distribution for the rare flavor-changing neutral current decay Bd⁰ → K*⁰( → K⁻π⁺)e⁺e⁻ is studied. The emphasis is placed on accurate treatment of the contribution from the processes Bd⁰ → ...
  • Ivashyn, S.A. (Вопросы атомной науки и техники, 2012)
    The form factor of the vector meson V conversion transition into the pseudoscalar meson Ρ and the lepton pair l⁺l⁻ is presented for V ≡ ρ⁰, ω, φ and Ρ ≡ π⁰, η. Our approach is based on the chiral effective field theory ...
  • Kotlyar, V.V.; Krupina, N.V. (Вопросы атомной науки и техники, 2012)
    Mechanisms of J/ψ, Υ and B meson production in proton-proton scattering at total energy 7 TeV are studied with the help of event generator Pythia 8. Uncertainties in the total and differential cross sections due to choice ...
  • Shebeko, A.V.; Frolov, P.A.; Dubovik, E.A. (Вопросы атомной науки и техники, 2012)
    It is shown that the method of unitary clothing transformations (UCT) developed in [1, 2] and applied to nuclear physics problems [3, 4], gives a fresh look at constructing interactions between the "clothed'' nucleons, ...
  • Zheltukhin, A.A. (Вопросы атомной науки и техники, 2012)
    The character of elastic forces of relativistic membranes and p-branes encoded in their nonlinear equations is studied. The toroidal brane equations are reduced to the classical equations of anharmonic elastic media ...
