ВОЗМОЖНОСТИ И ПЕРСПЕКТИВЫ МОДЕРНИЗАЦИИ ПОЛИТИЧЕСКОЙ И ЭКОНОМИЧЕСКОЙ ЖИЗНИ РОССИИ

Past some years after collapse of the USSR, a party most members of which are regarded by country people as «swindlers» and «thieves» has come to power in Russia and remains there at present. Corruption, fraud and other criminal phenomena blossom in Russia, since there is no struggle against them. State machinery bureaucrats consume 40% of the GIP. Modernization of the country’s political and economic life is possible only through fundamental break of current public relations and taking new orientation on the basis of a combination of capitalist and socialist features.Через некоторое время после распада СССР в России к власти пришла и удерживается до сих пор партия, большинство членов которой народ считает «жуликами» и «ворами». В России безнаказанно процветают коррупция, мошенничество и прочие криминальные явления. Работники госаппарата поглощают 40% ВВП. Модернизация политической и экономической жизни страны возможна лишь путем коренной ломки сложившихся общественных отношений и установления их новой ориентации на основе сочетания элементов капитализма и социализма

Исследование оптоэлектронного датчика угловых смещений на основе глубокой отражательной фазовой дифракционной решётки

An optoelectronic device for measurements of small angular displacements based on a diffraction of a laser beam on a deep reflective phasetype grating was suggested and investigated. The grating's depth is about several wavelengths. The zero diffraction order's power dependency on the incident angle of a laser beam was investigated theoretically and experimentally. There were found conditions when linear conversion of angular vibrations into changes of power of zero order took place. The experimentally measured sensitivity of the device was rad with channel bandwidth of 800 Hz and signal-to-noise ratio 10.Предложен и исследован оптоэлектронный датчик малых угловых перемещений на основе дифракции лазерного пучка на глубокой отражательной фазовой дифракционной решётке. Проведён теоретический анализ и экспериментальные исследования характеристик датчика

The COMPASS Experiment at CERN

The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or more outgoing particles are detected in coincidence with the incoming muon or hadron. A large polarized target inside a superconducting solenoid is used for the measurements with the muon beam. Outgoing particles are detected by a two-stage, large angle and large momentum range spectrometer. The setup is built using several types of tracking detectors, according to the expected incident rate, required space resolution and the solid angle to be covered. Particle identification is achieved using a RICH counter and both hadron and electromagnetic calorimeters. The setup has been successfully operated from 2002 onwards using a muon beam. Data with a hadron beam were also collected in 2004. This article describes the main features and performances of the spectrometer in 2004; a short summary of the 2006 upgrade is also given.Comment: 84 papes, 74 figure

The Deuteron Spin-dependent Structure Function g1d and its First Moment

We present a measurement of the deuteron spin-dependent structure function g1d based on the data collected by the COMPASS experiment at CERN during the years 2002-2004. The data provide an accurate evaluation for Gamma_1^d, the first moment of g1d(x), and for the matrix element of the singlet axial current, a0. The results of QCD fits in the next to leading order (NLO) on all g1 deep inelastic scattering data are also presented. They provide two solutions with the gluon spin distribution function Delta G positive or negative, which describe the data equally well. In both cases, at Q^2 = 3 (GeV/c)^2 the first moment of Delta G is found to be of the order of 0.2 - 0.3 in absolute value.Comment: fits redone using MRST2004 instead of MRSV1998 for G(x), correlation matrix adde

A new measurement of the Collins and Sivers asymmetries on a transversely polarised deuteron target

New high precision measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarised 6LiD target are presented. The data were taken in 2003 and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. Both the Collins and Sivers asymmetries turn out to be compatible with zero, within the present statistical errors, which are more than a factor of 2 smaller than those of the published COMPASS results from the 2002 data. The final results from the 2002, 2003 and 2004 runs are compared with naive expectations and with existing model calculations.Comment: 40 pages, 28 figure

Spin asymmetry A_1^d and the spin-dependent structure function g_1^d of the deuteron at low values of x and Q^2

We present a precise measurement of the deuteron longitudinal spin asymmetry A_1^d and of the deuteron spin-dependent structure function g_1^d at Q^2 < 1 GeV^2 and 4*10^-5 < x < 2.5*10^-2 based on the data collected by the COMPASS experiment at CERN during the years 2002 and 2003. The statistical precision is tenfold better than that of the previous measurement in this region. The measured A_1^d and g_1^d are found to be consistent with zero in the whole range of x.Comment: 17 pages, 10 figure

Gluon polarization in the nucleon from quasi-real photoproduction of high-pT hadron pairs

We present a determination of the gluon polarization Delta G/G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q^2<1(GeV/c)^2, with a pair of large transverse-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon beam scattered on a polarized 6-LiD target. The helicity asymmetry for the selected events is = 0.002 +- 0.019(stat.) +- 0.003(syst.). From this value, we obtain in a leading-order QCD analysis Delta G/G=0.024 +- 0.089(stat.) +- 0.057(syst.) at x_g = 0.095 and mu^2 =~ 3 (GeV}/c)^2.Comment: 10 pages, 3 figure

Measurement of the Spin Structure of the Deuteron in the DIS Region

We present a new measurement of the longitudinal spin asymmetry A_1^d and the spin-dependent structure function g_1^d of the deuteron in the range 1 GeV^2 < Q^2 < 100 GeV^2 and 0.004< x <0.7. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarised muon beam and a large polarised 6-LiD target. The results are in agreement with those from previous experiments and improve considerably the statistical accuracy in the region 0.004 < x < 0.03.Comment: 10 pages, 6 figures, subm. to PLB, revised: author list, Fig. 4, details adde
