New method of accounting for interference contributions within a multipheriperal model
We consider an inelastic scattering of protons within the simplest real
scalar model (phi-cubed). Although this model is being studied for a
very long time, the problem of accounting for the interference contributions
for all the possible particle multiplicities observed in experiment is not
solved yet. We propose the method which is based on grouping of the
interference contributions into sets in such a way that the sum of all
interference contributions of each particular set can be calculated with
Laplace's method. This approach allowed us to calculate all the interference
contributions to the cross-sections for multiplicities up to at
the energy GeV. The obtained models of the energy
dependence of total scattering cross-section and the inclusive rapidity
distribution are in qualitative agreement with the experiment. We also consider
the well known effect of the energy dependence of the shape of inclusive
rapidity distribution, and propose an explanation of this dependence and
consider it exactly as the interference effect.Comment: 13 pages, 10 figure
Galactic Cosmic Rays and Insolation are the Main Drivers of Global Climate of the Earth
An energy-balance model of global climate, which takes into account a
nontrivial role of galactic cosmic rays, is developed. The model is described
by the fold catastrophe equation relative to increment of temperature, where
galactic cosmic rays and insolation are control parameters. The comparison of
the results of a computer simulation of time-dependent solution of the
presented model and oxygen isotope records of deep-sea core V28-238 over the
past 730 kyr are presented. The climate evolution in future 100 kyr is also
predicted.Comment: 11 pages, 3 figure
Impulse source of high energy neutrons emitted by fusion reactions after compression of D-T gas by cumulative detonation waves
We develop the physical model and the system of equations for the impulse
neutron source (INS) of high-energy neutrons (14 MeV) emitted by fusion
reactions during compression of D-T gas by cumulative detonation waves. The
system of INS equations includes a system of gas dynamic equations that takes
into account the energy transfer by radiation, equations for the radiation
flux, the equation of the shock adiabat (the Hugoniot adiabat) for a compressed
gas, and the equation for the neutron yield. We perform the INS dynamics
simulation for the spherical and cylindrical geometries, and calculate maximum
temperatures of D-T plasma, its density and neutron yield in the pulse. The
obtained temperature estimates and simulation results show that the
thermonuclear fusion temperatures are reached within this approach, and the
fusion reactions proceed. Their yield determines the yield of neutrons.Comment: 10 pages, 3 figures, 3 table
Geoantineutrino Spectrum and Slow Nuclear Burning on the Boundary of the Liquid and Solid Phases of the Earth's core
The problem of the geoantineutrino deficit and the experimental results of
the interaction of uranium dioxide and carbide with iron-nickel and
silica-alumina melts at high pressure (5-10 GPa) and temperature (1600- 22000
C) have induced us to consider the possible consequences of made by V.
Anisichkin and A. Ershov supposition that there is an actinoid shell on
boundary of liquid and solid phases of the Earth's core. We have shown that the
activation of a natural nuclear reactor operating as the solitary waves of
nuclear burning in 238U- and/or 232Th-medium (in particular, the
neutron-fission progressive wave of Feoktistov and/or Teller-Ishikawa-Wood)
such physical consequent can be. The simplified model of the kinetics of
accumulation and burnup in U-Pu fuel cycle of Feoktistov is developed. The
results of the numerical simulation of neutron-fission wave in two-phase UO2/Fe
medium on a surface of the Earth's solid core are presented. On the basis of
O'Nions-Ivensen-Hamilton model of the geochemical evolution of mantle
differentiation and the Earth's crust growth supplied by actinoid shell on the
boundary of liquid and solid phases of the Earth's core as a nuclear energy
source, the tentative estimation of intensity and geoantineutrino spectrum on
the Earth surface was obtained.Comment: 26 pages, 7 figure
Does the problem of global warming exist at all? Insight from the temperature drift induced by inevitable colored noise
In the present paper we state a problem of the colored noise nonremovability
on the climatic 30-year time scale, which essentially changes the angle of view
on the known problem of global warming.Comment: 9 pages, 4 figure
The Inverse Problem of Remote Neutrino Diagnostics of Intrareactor Processes
Using the well-known experimental data the inverse problem of neutrino
diagnostics of reactor core is considered. The solution of this problem makes
it possible to determine distantly the current value of nuclear density of each
nuclear fuel components with known accuracy and also opens up the possibility
for the development of neutrino online technology of temporal evolution of
nuclear fuel isotopic structure and reactor power.Comment: 17 pages, 3 figure
Can Resonant Oscillations of the Earth Ionosphere Influence the Human Brain Biorhythm?
Within the frames of Alfv\'en sweep maser theory the description of
morphological features of geomagnetic pulsations in the ionosphere with
frequencies (0.1-10 Hz) in the vicinity of Schumann resonance (7.83 Hz) is
obtained. It is shown that the related regular spectral shapes of geomagnetic
pulsations in the ionosphere determined by "viscosity" and "elasticity" of
magneto-plasma medium that control the nonlinear relaxation of energy and
deviation of Alfv\'en wave energy around its equilibrium value. Due to the fact
that the frequency bands of Alfv\'{e}n maser resonant structures practically
coincide with the frequency band delta- and partially theta-rhythms of human
brain, the problem of degree of possible impact of electromagnetic "pearl" type
resonant structures (0.1-5 Hz) onto the brain bio-rhythms stability is
discussed.Comment: 13 pages, 9 figure
Axion mechanism of Sun luminosity: light shining through the solar radiation zone
It is shown that the hypothesis of the axion mechanism of Sun luminosity
suggesting that the solar axion particles are born in the core of the Sun and
may be efficiently converted back into -quanta in the magnetic field of
the solar overshoot tachocline is physically relevant. As a result, it is also
shown that the intensity variations of the -quanta of axion origin,
induced by the magnetic field variations in the tachocline, directly cause the
Sun luminosity %and total solar irradiance (TSI) variations and eventually
characterize the active and quiet states of the Sun.
Within the framework of this mechanism estimations of the strength of the
axion coupling to a photon () and
the hadronic axion particle mass () have been
obtained. It is also shown that the claimed axion parameters do not contradict
any known experimental and theoretical model-independent limitations.Comment: 36 pages, 17 figures (v3: substantially revised paper, also taking

Superluminal neutrinos and quantum cross-correlation theory of neutrino source location
Based on the developed cross-correlation theory for remote location of
neutrino source with two-detector setup for neutrino detection the modification
of arrangement of the OPERA experiment is suggested. Within the framework of
computing experiment based on the OPERA experimental data we show that the use
of this theory makes it possible not only to determine with high accuracy the
delay time between neutrino signals but to eliminate the errors of blind
analysis by which all necessary time corrections for determination of signal
"technologically unremovable" delay time between CERN and GSL are performed.Comment: 6 pages, 3 figure
An Alternative Method for Solving Two Problems of the Standard Model
Two problems of the Standard Model, associated with the introduction of
non-gauge interactions and with the introduction of an electromagnetic field as
a linear combination of fields on which various gauge groups are implemented,
are analyzed. It is noticed that the existing model contains phase uncertainty of the matrix elements of the raising and lowering
generators of the group. This uncertainty creates the
condition for the additional local symmetry of the
Standard Model Lagrangian with respect to the choice of various equivalent
generator representations of the group, which is provided
by the electromagnetic field. In this case, due to the different action of the
raising and lowering generators on the fields of each generation of leptons and
quarks, these fields interact with the electromagnetic field in different ways.
It is also shown that considering the multi-particle gauge field a description
of the Higgs mechanism can be obtained, free from the shortcomings of the
well-known single-particle description, the main of which is the introduction
of the non-gauge "phi-four" interaction, that is not reduced to the fundamental
one. In the proposed model, the spontaneous symmetry breaking is achieved due
to the same fundamental interaction, the mediating particle mass of which it
provides.Comment: 34 pages, 1 figur
