On the origin of the discrepancy between the expected and observed results at KamLAND
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
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
as a secondary symmetry group, and in this
connexion we briefly discuss logically possible aspects of the -violation in
weak interactions.Comment: 10 pages, LaTeX, no figure
Toward an Infinite-component Field Theory with a Double Symmetry: Free Fields
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
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. V3 is a journal version with a

Double Symmetry and Infinite-Component Field Theory
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. Talk given at the Fifth International

Magnetic moment operator of non-Dirac particles and some elements of polarization -experiments
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 -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
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 -mesons
consists of two elements, and ; the states and
do not exist as physical objects (in the form of particles or
"particle mixtures"); the absence of the states and
destroys the grounds for introducing the notion of their oscillations, further
replicated as the neutrino oscillation concept. The conclusions concerning the
neutral -mesons are also applicable to the neutral -, - and
-mesons.Comment: 7 pages, v2: New emphasis in the tex
Toward an Infinite-component Field Theory with a Double Symmetry: Interaction of Fields
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
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
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: ,
