  • From theory to experiment: hadron electromagnetic form factors in space-like and time-like regions 
    Tomasi-Gustafsson, E.; Gakh, G.I.; Rekalo, A.P. (Вопросы атомной науки и техники, 2007)
    Hadron electromagnetic form factors contain information on the intrinsic structure of the hadrons. The pioneering work developed at the Kharkov Physical-Technical Institute in the 60's on the relation between the polarized ...
  • Elimination of power divergences in consistent model for spinless and high-spin particle interactions 
    Kulish, Yu.V.; Rybachuk, E.V. (Вопросы атомной науки и техники, 2007)
    The currents for the interaction of the massive high-spin boson (J≥1) with two spinless particles are derived. These currents obey the theorem on currents and fields as well as the theorem on current asymptotics. In one-loop ...
  • T-odd correlations in B±→D*K*± decays 
    Kovalchuk, V.A. (Вопросы атомной науки и техники, 2007)
    We examine T violating triple product correlations in the processes B±→D* K*±, D*→Dπ⁰, Dγ, D→f, where the neutral D(D*) meson is a superposition of D⁰(D*⁰) and D⁰(D*⁰). It is shown that large T violating asymmetries (~18% ...

    Kotlyar, V.; Nogga, A. (Вопросы атомной науки и техники, 2007)
    Tensor and operator representations for wave function (WF) of three–nucleon bound states are discussed. It is supposed that space parity is not conserved in interaction between nucleons. The WFs of ³He and ³H are expressed ...

    A model for description of electromagnetic form factors of the charged and neutral kaons in the energy region √s ~ 1-2 GeV is presented. Our approach is based on extended vector-meson-dominance model. It accounts for ...
  • The spontaneous generation of magnetic fields at high temperature in SU(2)-gluodynamics on a lattice 
    Demchik, V.I.; Skalozub, V.V. (Вопросы атомной науки и техники, 2007)
    In a lattice formulation of the SU(2)-gluodynamics, the spontaneous generation of the chromomagnetic field at high temperature is investigated. The procedure to study this phenomenon is developed and Monte Carlo simulations ...
  • Covariant amplitude decomposition in relativistic fermion scattering problems 
    Bondarenko, M.V. (Вопросы атомной науки и техники, 2007)
    A parameterization of on-mass-shell relativistic fermion scattering amplitudes by a set of 4 covariant amplitudes is proposed, which in the non-relativistic limit turn to coefficients of the matrix amplitude decomposition ...
  • The high-Z hydrogen-like atom: a model for polarized structure functions 
    Artru, X.; Benhizia, K. (Вопросы атомной науки и техники, 2007)
    The Dirac equation offers a precise analytical description of relativistic two-particle bound states, when one of the constituent is very heavy and radiative corrections are neglected. Looking at the high-Z hydrogen-like ...
  • Single–spin asymmetries in electron–proton and photon-proton scattering in the Bethe–Heitler processes induced by loop corrections

  • The θ-twistor versus the supertwistor 
    Zheltukhin, A.A. (Вопросы атомной науки и техники, 2007)
    We introduce the θ-twistor, which is a new supersymmtric generalization of the Penrose twistor and is also alternative to the supertwistor. The θ-twistor is a triple of spinors including the spinor θ extending the Penrose’s ...
