The Riemann-Cartan space in the O-theory
Nonrelativistic equation of particle with a spin for the Lagrangian on a
nonassociative algebra is obtained. It is shown that in this model arises
Riemann-Cartan space. In the case of central symmetry in addition to the
pseudo-curvature appears torsion as pseudovector that interacts with the spin
of the particle. An estimation of the influence of torsion on the strength of
gravitational attraction in the central gravitational field is given.Comment: 12 page
Spontaneous symmetry breaking for long-wave gravitons in the early Universe
It is shown that nonlinear terms in equations of gravitons on the background
of curved space-time of the expanding Universe can solve the problem of the
negative square of the effective mass formally arising in linear approximation
for gravitons. Similar to well known spontaneous breaking of symmetry in
Goldstone model one must take another vacuum so that nonzero vacuum expectation
value of the quantized graviton field leads to change of spectrum for
gravitons. There appears two graviton fields, one with the positive mass,
another with the zero mass. Energy density and the density of particles created
by gravitation of the expanding Universe are calculated for some special cases
of the scale factor. Numerical results are obtained for the dust universe case.Comment: 13 page
Absolute Calibration of a Large-diameter Light Source
A method of absolute calibration for large aperture optical systems is
presented, using the example of the Pierre Auger Observatory fluorescence
detectors. A 2.5 m diameter light source illuminated by an ultra--violet light
emitting diode is calibrated with an overall uncertainty of 2.1 % at a
wavelength of 365 nm.Comment: 15 pages, 8 figures. Submitted to JINS
Information-hardware support of systems of the automated electromagnetic monitoring of geodynamic objects
In article the structure of an informational-hardware support of the automated system of data processing at electromagnetic monitoring of geodynamic objects is considered. The structure of interrelations of the object-oriented and serving subsystems realizing methodological, program and technical and information support of processes of filing and data processing of geodynamic monitoring is define
Zero mode effect in the four quark states
We calculate the masses of the four quark states which decay
dominantly into and respectively by QCD sum rules approach.
We include the zero mode contribution and find it plays an important role in
the sum rules. We predict that the masses of the states and
both are 1.4-1.5 GeV. This is close to the experimental candidates
and .Comment: 5 pages, 4 Postscript figure

Conductivity in Two-Dimensional Disordered Model with Anisotropic Long-Range Hopping
We consider two-dimensional system of particles localized on randomly
distributed sites of squared lattice with anisotropic transfer matrix elements
between localized sites. By summing of "diffusion ladder" and "cooperon ladder"
type vertices we calculated the conductivity for various sites and particles
densities.Comment: Latex, 10 page
