  • On some properties of 2-D Weyl equation for charged massless spin ½ particle 
    Ovcharenko, I.E.; Stepanovsky, Yu.P. (Вопросы атомной науки и техники, 2007)
    We discuss some properties of Dirac equation and 2-D Weyl equation for a charged massless spin ½ particle in a stationary inhomogeneous magnetic field such as Bloch theorem and Aharonov-Casher theorem and its relation to ...
  • Properties of high–spin boson interaction currents and elimination of power divergences 
    Kulish, Yu.V.; Rybachuk, E.V. (Вопросы атомной науки и техники, 2001)
    The problem of the elimination of the power divergences for the interactions of the high-spin bosons (J≥1) is investigated. It is proved that in the consistent theory the high-spin boson interaction currents and the field ...
  • Rotated charged black holes in Einstein-Born-Infeld theories 
    Diego Julio Cirilo Lombardo (Вопросы атомной науки и техники, 2001)
    In this work the solution of the Einstein equations for slowly rotating black hole with Born-Infeld charge is obtained. Geometrical properties, singularities, horizons of this solution are analyzed. There are considered ...
  • Supersymmetric 3-brane from the extended Goldstone-Maxwell supermultiplet 
    Kapustnikov, A.; Shcherbakov, A. (Вопросы атомной науки и техники, 2001)
    A new gauge supermultiplet of the N=2, D=4 supersymmetry with the complex central charge is proposed. Besides the global N=2, D=4 supersymmetry it possesses the symmetry under the central charge transformations and the ...
  • Tensionless super p-branes in extended superspaces 
    Uvarov, D.V.; Zheltukhin, A.A. (Вопросы атомной науки и техники, 2007)
    Analyzed is the symmetry structure of tensionless super p-branes in N=1 superspace enlarged by commuting antisymmetric tensor coordinates zm1 - mp associated to tensorial central charge generators of N=1 extended superalgebra. ...
  • The method of unitary clothing transformations in quantum field theory: the bound-state problem and the S-matrix 
    Shebeko, A.V. (Вопросы атомной науки и техники, 2007)
    Being aimed at reformulating quantum field theory (QFT) within the notion of the so-called clothed particles and interactions between them we consider the problem of finding the simplest eigenstates of the total field ...
  • The twistor string: a new framework to study Yang-Mills theories, and its spacetime formulation 
    Bandos, I.A.; de Azcárraga, J.A.; Miquel-España, C. (Вопросы атомной науки и техники, 2007)
    We give a brief review of the twistor string approach to supersymmetric Yang-Mills theories with an emphasis on the different formulations of (super)string models in supertwistor space and their superspace form. We discuss ...
  • 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 ...
  • Transition amplitude for free massless particle 
    Zima, V.G.; Fedoruk, S.A. (Вопросы атомной науки и техники, 2001)
    The propagator for massless particle of arbitrary spin is represented as BFV-BRST path integral in index spinor formalism. The classical formulation of the theory is investigated and it is carried out its Hamiltonization ...
  • Twistorial superparticle with tensorial central charges 
    Fedoruk, S.A.; Zima, V.G. (Вопросы атомной науки и техники, 2001)
    A twistorial formulation of the N=1 D=4 superparticle with tensorial central charges describing massive and massless cases in uniform manner is given. The twistors resolve energy-momentum vector whereas the tensorial central ...
  • Vertex clothing in quantum field theory 
    Korda, V.Yu.; Yeletskikh, I.V. (Вопросы атомной науки и техники, 2007)
    The problem of the vertex renormalization in quantum field theory is tackled via the implementation of the unitary clothing transformation method. In the model of charged spinless nucleon and scalar meson fields coupled ...
