Солитоны в обобщенной квантовой гидродинамике и теория шаровой молнии
No full textQuantum solitons are discovered with the help of generalized quantum hydrodynamics. The solitons have the character of the stable quantum objects in the self consistent electric field. The theory of quantum solitons lead to explanation of the existence of stable atom structures on the microscopic level and lightning balls on the macroscopic level of description of physical systems. The delivered theory demonstrates the great possibilities of the generalized quantum hydrodynamics in investigation of the quantum solitons. The paper can be considered also as comments and prolongation of the materials published in the known author`s monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004). The theory leads to solitons as typical formations in the generalized quantum hydrodynamics.Квантовые солитоны открыты с помощью обобщенной квантовой гидродинамики. Солитоны имеют характер стабильных квантовых объектов в самосогласованном электрическом поле. Теория квантовых солитонов приводит к объяснению существования стабильных атомов на микроскопическом уровне и шаровых молний на макроскопическом уровне описания физических систем. Разработанная теория демонстрирует большие возможности обобщенной квантовой гидродинамики в исследовании квантовых солитонов как типичных образований в обобщенной квантовой теории. Статья может также рассматриваться как продолжение исследований, изложенных в известной монографии автора (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. – Elsevier, 2004)
К обобщенной релятивистской кинетической и гидродинамической теории
No full textOn the basis of statistical description the movement of relativistic particles without external forces is considered. The hydrodynamic form of the Dirac equation is suggested. The Lorentz invariant form of the non-local Alexeev equation (generalized Boltzmann equation) was obtained. These results lead to the possibility of construction of relativistic quantum hydrodynamics. This paper can also be considered as continuation of the known monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004).На основе статистического описания рассматривается движение релятивистских частиц без учета внешних сил. Представлена гидродинамическая форма уравнения Дирака. Получена лоренц-инвариантная форма нелокального кинетического уравнения Алексеева (обобщенного уравнения Больцмана), что открывает возможность построения обобщенной релятивистской квантовой гидродинамики. Статья может также рассматриваться как продолжение исследований, изложенных в известной монографии. (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004)

No full textIncome Distribution and Price Controls: Targeting a Social Safety Net During Economic Transition
No full textDuring the ongoing post-communist economic transitions, the relative well-being of many people is changing rapidly, and governments are not well positioned to accurately measure individual living standards. Under such circumstances, continued price controls over basic consumer goods within the state sector, and the associated queuing, can form a serviceable device for targeting poor people for subsidies. With a fixed-price state sector and free-price parallel markets, rich people might choose to avoid queues and shop in the free markets, while poor people would prefer to pay low nominal prices and queue in the state sector. The targeting of subsidies through queues, therefore, can be accomplished even if the government has no information on individual income or living standards. When the alternative to price controls is a poorly targeted explicit social safety net, the resource cost of queues might be more than compensated for by an improvement in the targeting of subsidies.price controls, tax evasion, queue-rationing, economic transition, income distribution

The deuteron spin-dependent structure function g(1)(d) and its first moment
No full textAlexakhin VY, Alexandrov Y, Alexeev GD, et al. The deuteron spin-dependent structure function g(1)(d) and its first moment. Phys.Lett. B. 2007;647(1):8-17.We present a measurement of the deuteron spin-dependent structure function g(1)(d) based on the data collected by the COMPASS experiment at CERN during the years 2002-2004. The data provide an accurate evaluation for Gamma(d)(1), the first moment of g(1)(d) (x), and for the matrix element of the singlet axial current, a(0). The results of QCD fits in the next to leading order (NLO) on all g(1) 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(x) is found to be of the order of 0.2-0.3 in absolute value. (c) 2007 Elsevier B.V. All rights reserved
Combined Tevatron upper limit on g g → H → W + W − and constraints on the Higgs boson mass in fourth-generation fermion models
No full textLimits on anomalous trilinear gauge boson couplings from WW, WZ and Wγ production in pp collisions at √ s = 1.96 TeV
No full textWe present searches for the anomalous γWW and ZWW trilinear gauge boson couplings from WW and W Z production using lepton plus dijet final states and a combination with results from Wγ , WW, and W Z production with leptonic final states. The analyzed data correspond to up to 8.6 fb−1 of integrated luminosity collected by the D0 detector in p¯p collisions at √ s = 1.96 TeV. We set the most stringent limits at a hadron collider to date assuming two different relations between the anomalous coupling parameters κγ , λ, and g Z 1 for a cutoff energy scale Λ = 2 TeV. The combined 68% C.L. limits are −0.057< κγ < 0.154, −0.015 < λ < 0.028, and −0.008< g Z 1 < 0.054 for the LEP parameterization, and −0.007< κ < 0.081 and −0.017 < λ < 0.028 for the equal couplings parameterization. We also present the most stringent limits of the W boson magnetic dipole and electric quadrupole moments
