  • AdS₄ x CP³ superstring as OSp(4|6)/(SO(1,3) x U(3)) sigma-model in conformal basis 
    Uvarov, D.V. (Вопросы атомной науки и техники, 2012)
    Basic features of Lagrangian formulation for AdS₄ x CP³ superstring in the framework of OSp(4|6)/(SO(1,3) x U(3)) sigma-model approach are reviewed with the emphasis on realization osp(4|6) background isometry superalgebra ...
  • A nonlocal extension of the Wentzel field model in the clothed-particle representation 
    Shebeko, A.V.; Frolov, P.A. (Вопросы атомной науки и техники, 2012)
    The clothed particle approach is applied to express the total Hamiltonian of interacting fields in terms of clothed particles. In order to avoid ultraviolet divergences typical of many field theories we introduce some ...
  • A way to incorporation of thermodynamics into quantum theory 
    Golubjeva, O.N.; Sukhanov, A.D. (Вопросы атомной науки и техники, 2012)
    We suggest an approach allowing restrict a gap between macro- and micro descriptions of nature (i.e. between statistical thermodynamics and quantum mechanics) on the basis of a new heat bath model in the form of cold and ...
  • Generalized hooke law for relativistic membranes and p-branes 
    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 ...
  • General properties of interaction currents of higher spin fermions and their consequences for πN–scattering 
    Kulish, Yu.V.; Rybachuk, E.V. (Вопросы атомной науки и техники, 2012)
    The model for the currents of interactions of higher spin fermions with the 0- and 1/2-spin particles is proposed. These currents obey to the theorem on currents and fields as well as the theorems on current asymptotics. ...
  • Grassmann dynamics of classical spin in nonabelian gauge fields 
    Pol’shin, S.A. (Вопросы атомной науки и техники, 2012)
    Using Grassmann variant of classical mechanics, we construct Lagrangian dynamics of classical spinning particle in (possibly non-abelian) gauge fields. Quantization of this model is briefly discussed.
  • Is a field-induced ferromagnetic phase transition in the magnetar core actually possible? 
    Isayev, А.А.; Yang, J. (Вопросы атомной науки и техники, 2012)
    Spin polarized states in dense neutron matter with BSk20 Skyrme force are considered in magnetic fields up to 10²⁰ G. It is shown that the appearance of the longitudinal instability in a strong magnetic field prevents the ...
  • Model-independent Z' searches at modern colliders 
    Gulov, A.V.; Kozhushko, A.A.; Skalozub, V.V.; Pankov, A.A.; Tsytrinov, A.V. (Вопросы атомной науки и техники, 2012)
    The model-independent constraints on the Abelian Z' couplings from the LEP data are applied to estimate the Z' production in experiments at hadron colliders. The Z' contribution to the Drell-Yan process at modern hadron ...
  • Necessary generalization of Кlein-Gordon and Dirac equations and existence of particle generations 
    Kulish, Yu.V.; Rybachuk, E.V. (Вопросы атомной науки и техники, 2012)
    It is shown that values of the Green functions for the Klein-Gordon and Dirac equations depend on calculation method. The integrals for the Green functions of new equations can converge if the minimal numbers of the particles ...
  • Nuclear interactions and multiple coulomb scattering at volume reflection 
    Bondarenco, M.V. (Вопросы атомной науки и техники, 2012)
    For volume reflection of charged particles governed by the continuous potential of atomic planes in a bent crystal, we calculate the probability of a nuclear interaction. It is found to differ from the corresponding ...
  • On 2D massless field wave equations 
    Ovcharenko, I.E.; Stepanovsky, Yu.P. (Вопросы атомной науки и техники, 2012)
    The 2D wave equations of massless fields with arbitrary spin are obtained by application of the Extended Little Lorentz Group. The possibility of the existence of an interaction of charged 2D massless fields of spin one ...
  • On the type of the temperature phase transition in O(N) models 
    Bordag, M.; Demchik, V.I.; Gulov, A.V.; Skalozub, V.V. (Вопросы атомной науки и техники, 2012)
    The temperature induced phase transition is investigated in the O(N) models by using graphics processing units (GPU) for Monte Carlo simulations on a lattice. General purpose computing on GPU (GPGPU) technology allows to ...
  • Renormalization the quantum field model of particle interaction 
    Tikhonov, V.I.; Tykhonov, A.V. (Вопросы атомной науки и техники, 2012)
    The model simulates the interaction of abstract entities distinguished in a physical experiment and denoted as particles. Empirical data results in the non-hermitian anti-symmetric matrix of particle relationship. The real ...
  • Spin, confinement, localization and supersymmetry 
    Cirilo-Lombardo, Diego Julio (Вопросы атомной науки и техники, 2012)
    New mechanism of localization of fields in a particular sector of a special supermanifold is proposed and described, based on previous works of the authors. Different aspects of this new mechanism are discussed as an ...
  • The problems of the account for energy-momentum conservation law and interference effects at hadron-hadron scattering 
    Sharf, I.V.; Tykhonov, A.V.; Deliyergiyev, M.A.; Sokhrannyi, G.O.; Podolyan, N.A.; Rusov, V.D. (Вопросы атомной науки и техники, 2012)
    We present the new method for the calculation of inelastic scattering cross-section, which doesn't require the use of any additional Regge-like assumptions and accurately accounts for energy-momentum conservation law. This ...
