    On the origin of the discrepancy between the expected and observed results at KamLAND

    Full text link
    After a logically clear and simple solution of the solar neutrino problem on the basis of the hypothesis about the existence of a new interaction involving electron neutrinos and nucleons, the question arose about the origin of the distinction between the expected and observed results of the experiment with reactor antineutrino at KamLAND. In the present work, a significant attenuation of light during its propagation in the KamLAND liquid scintillator is noted, the effect of which on the observability of the expected inverse beta-decay events and on the reconstruction of their characteristics has not been adequately analyzed. Because of this, we do not consider the declared results of the KamLAND experiment as reliable.Comment: 6 pages. Significant additions, editorial change

    Double Symmetries in Field Theories

    Get PDF
    In the paper a concept of a double symmetry is introduced, and its qualitative characteristics and rigorous definitions are given. We describe two ways to construct the double-symmetric field theories and present an example demonstrating the high efficiency of one of them. In noting the existing double-symmetric theories we draw attention at a dual status of the group SU(2)L⊗SU(2)RSU(2)_{L} \otimes SU(2)_{R} as a secondary symmetry group, and in this connexion we briefly discuss logically possible aspects of the PP-violation in weak interactions.Comment: 10 pages, LaTeX, no figure

    Toward an Infinite-component Field Theory with a Double Symmetry: Free Fields

    Get PDF
    We begin a study of possibilities of describing hadrons in terms of monolocal fields which transform as proper Lorentz group representations decomposable into an infinite direct sum of finite-dimensional irreducible representations. The additional requirement that the free-field Lagrangians be invariant under the secondary symmetry transformations generated by the polar or the axial four-vector representation of the orthochronous Lorentz group provides an effective mechanism for selecting the class representations considered and eliminating an infinite number of arbitrary constants allowed by the relativistic invariance of the Lagrangians.Comment: 16 pages, LaTeX, no figure

    Mass Spectra in the Doubly Symmetric Theory of Infinite-Component Fields

    Full text link
    We consider the problem of the characteristics of mass spectra in the doubly symmetric theory of fields transforming under the proper Lorentz group representations decomposable into an infinite direct sum of finite-dimensional irreducible representations. We show that there exists a range of free parameters of the theory where the mass spectra of fermions are quite satisfactory from the physical standpoint and correspond to the picture expected in the parton model of hadrons.Comment: 14 pages, 4 figures, 1 table, LaTeX.

    Double Symmetry and Infinite-Component Field Theory

    Full text link
    Qualitative characteristics and the rigorous definition of a concept of the double symmetry is given. We use some double symmetry for constructing a theory of fields not investigated before which transform as the proper Lorentz group representations decomposable into infinite direct sums of finite-dimentional irreducible representations. All variants of the double-symmetric free Lagrangian of such fields are in brief described. The solution of the problem of changing Lagrangian mass terms due to a spontaneous breaking of the secondary symmetry is stated. The general properties of the mass spectra of fermions in the considered theory are given. It is pointed out a region of free parameters where the theoretical mass spectra qualitatively correspond to a picture typical for the parton model of hadrons.Comment: 9 pages, 2 figures, LaTeX.

    Magnetic moment operator of non-Dirac particles and some elements of polarization epep-experiments

    Full text link
    An explicit form of the magnetic moment tensor operator for non-Dirac particles with rest spin 1/2 and its essential difference from the spin operator are established. Possible consequences of the last fact for the description of the spin rotation in the magnetic field and for the values of magnetic moments of some nuclei, as well as the impact of this and other facts on the validity of modelling the azimuthal asymmetry of the secondary-scattered protons in epep-experiments are noted.Comment: 10 pages; v2 journal version with a modified introductio

    About neutral mesons and particle oscillations in the light of field-theoretical prescriptions of Weinberg

    Full text link
    By extending the well-known Weinberg's prescriptions on the diagonalization of the mass term of the Lagrangian without increasing the total number of entities, we get the following conclusions: the set of neutral KK-mesons consists of two elements, KS0K_{S}^{0} and KL0K_{L}^{0}; the states K0K^{0} and Kˉ0\bar{K}^{0} do not exist as physical objects (in the form of particles or "particle mixtures"); the absence of the states K0K^{0} and Kˉ0\bar{K}^{0} destroys the grounds for introducing the notion of their oscillations, further replicated as the neutrino oscillation concept. The conclusions concerning the neutral KK-mesons are also applicable to the neutral DD-, BB- and BsB_{s}-mesons.Comment: 7 pages, v2: New emphasis in the tex

    Toward an Infinite-component Field Theory with a Double Symmetry: Interaction of Fields

    Full text link
    We complete the first stage of constructing a theory of fields not investigated before; these fields transform according to Lorentz group representations decomposable into an infinite direct sum of finite-dimensional irreducible representations. We consider only those theories that initially have a double symmetry: relativistic invariance and the invariance under the transformations of a secondary symmetry generated by the polar or the axial four-vector representation of the orthochronous Lorentz group. The high symmetry of the theory results in an infinite degeneracy of the particle mass spectrum with respect to spin. To eliminate this degeneracy, we postulate a spontaneous secondary-symmetry breaking and then solve the problems on the existence and the structure of nontrivial interaction Lagrangians.Comment: 13 pages, LaTeX, no figure

    Some field-theoretical aspects of two types of the Poincare group representations

    Full text link
    The capabilities of some approaches to the relativistic description of hadronic states with any rest spin are analysed. The key feature in the Wigner's construction of irreducible representations of the Poincare group which makes this construction fruitless in the particle physics is picked out. A realization of unitary irreducible representations of the Poincare group of the standard type, which yet have never been considered, is discussed. The viability of the description of hadrons by the Poincare group representations of the standard type in the space of the infinite-component ISFIR-class fields is pointed out.Comment: 25 page

    Hypothesis about semi-weak interaction and experiments with solar neutrinos

    Full text link
    A new concept is proposed to solve the solar neutrino problem, that is based on a hypothesis about the existence of semi-weak interaction of electron neutrinos with nucleons mediated by massless pseudoscalar bosons. Owing to about 10 collisions of a solar neutrino with nucleons of the Sun, the fluxes of left- and right-handed solar neutrinos at the Earth surface are approximately equal, and their spectrum is changed in comparison with the one at the production moment. The postulated model with one free parameter provides a good agreement between the calculated and experimental characteristics of the processes with solar neutrinos: 37Cl→37Ar{}^{37}{\rm Cl} \rightarrow {}^{37}{\rm Ar}, 71Ga→71Ge{}^{71}{\rm Ga} \rightarrow {}^{71}{\rm Ge}, νee−→νee−\nu_{e} e^{-}\rightarrow \nu_{e} e^{-}, and νeD→e−pp\nu_{e}D \rightarrow e^{-}pp.Comment: 12 pages.
