    New method of accounting for interference contributions within a multipheriperal model

    Full text link
    We consider an inelastic scattering of protons within the simplest real scalar model ϕ3\phi^3 (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 n∼50 n\sim 50 at the energy s∼50 \sqrt{s} \sim 50 GeV. The obtained models of the energy dependence of total pppp 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

    Full text link
    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

    Full text link
    We develop the physical model and the system of equations for the impulse neutron source (INS) of high-energy neutrons (∼\sim14 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

    Full text link
    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

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?

    Full text link
    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

    Full text link
    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 γ\gamma-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 γ\gamma-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 (gaγ=3.6⋅10−11GeV−1g_{a \gamma} = 3.6 \cdot 10^{-11} GeV^{-1}) and the hadronic axion particle mass (ma∼2.3⋅10−2eVm_a \sim 2.3 \cdot 10^{-2} eV) 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 into account new experiments

    Superluminal neutrinos and quantum cross-correlation theory of neutrino source location

    Full text link
    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

    Full text link
    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 U(1)−U\left( 1 \right)- phase uncertainty of the matrix elements of the raising and lowering generators of the SU(2)SU\left( 2 \right) group. This uncertainty creates the condition for the additional local U(1)−U\left( 1 \right)- symmetry of the Standard Model Lagrangian with respect to the choice of various equivalent generator representations of the SU(2)SU\left( 2 \right) 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
