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

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.

The monitoring of the irregular disturbances in the arctic on the basis of the processing data of the distributed network of the geophysical observatories

The article discusses a data processing method for geomagnetic field of the earth on a distributed network of geophysical observatories. The proposed method allows to detect and monitor irregular disturbances of the geomagnetic field, evaluate their options, determine the epicenter of the occurrence of disturbances and to estimate the parameters of the epicente

Spatio-temporal data processing of automated geodynamic monitoring system

System In this paper, an approach to the organization of spatial-temporal processing of geoelectrical data in the system of automated geodynamic control is considered. It allows combining methodical, algorithmic, program and information support of the processes of collecting and processing of geodynamic information at subjects to contro

Determination of the preliminary phase of the facility destruction based on the resistance-acoustic method of control

The article substantiates the use of the resistance-acoustic method in problems of non-destructive testing of mechanical stresses or defects in structures of metals and alloys in natural and technical systems. The possibilities of the use of the proposed method for the potential monitored facilities were analyzed, to which the strict requirements for operational security are imposed (bearing reinforced concrete structures, bridges, radio and television towers, etc.

The article is devoted to the development of algorithmic support of the inclinometric control system built on the basis of accelerometers using the phase-metric method. This system is used to automated control the deviation of the angular parameters of the building axis from the vertica

A search for J^{PC}=1^{-+} exotic mesons in the pi- pi- pi+ and pi- pi0 pi0 systems

A partial wave analysis (PWA) of the pi-pi-pi+ and pi-pi0pi0 systems produced in the reaction pi- p -> (3pi)-p at 18 GeV/c was carried out using an isobar model assumption. This analysis is based on 3.0M pi-pi0pi0 events and 2.6M pi-pi-pi+ events and shows production of the a2(1320), pi2(1670) and \pi(1800) mesons. An earlier analysis of 250K pi-pi-pi+ events from the same experiment showed possible evidence for a J^{PC}=1^{-+}$ exotic meson with a mass of 1.6 GeV/c^2 decaying into rho pi. In this analysis of a higher statistics sample of the (3pi)- system in two charged modes we find no evidence of an exotic meson.Comment: 4 pages, 5 figures, added comment about the negative reflectivity exotic wave
