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)
Обобщенная квантовая гидродинамика
No full textThis paper addresses the fundamental principles of generalized Boltzmann physical kinetics, as a part of non-local physics. It is shown that the theory of transport processes (including quantum mechanics) can be considered in the frame of unified theory based on the non-local physical description. 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).В статье рассматриваются фундаментальные принципы обобщенной Больцмановской физической кинетики как составной части нелокальной физики. Установлено, что теория процессов переноса (включая квантовую механику) может быть рассмотрена в рамках универсальной теории, основанной на нелокальном физическом описании. Статья может рассматриваться как продолжение исследований, опубликованных в известной монографии автора (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004)

Measurement of the pp →W +b + X production cross section at √ s = 1.96 TeV
No full textWe present a measurement of the cross section for W boson production in association with at least one b-quark jet in proton–antiproton collisions. The measurement is made using data corresponding to an integrated luminosity of 6.1 fb−1 recorded with the D0 detector at the Fermilab Tevatron p¯p √ Collider at s = 1.96 TeV. We measure an inclusive cross section of σ(W(→μν) + b + X) = 1.04 ± 0.05 (stat.) ± 0.12 (syst.) pb and σ(W(→eν)+b+ X) = 1.00±0.04 (stat.)±0.12 (syst.) pb in the phase space defined by pνT > 25 GeV, pb-jet T > 20 GeV
Search for the standard model Higgs boson in the ZH →ν¯νb¯b channel in 9.5 fb−1 of p¯p collisions at √ s = 1.96 TeV
No full textWe present a search for the standard model Higgs boson in 9.5 fb−1 of p¯p collisions at √ s = 1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. The final state considered contains a pair of b jets and is characterized by an imbalance in transverse energy, as expected from p¯p → ZH → ν¯ν b¯b production. The search is also sensitive to the WH → νb¯b channel when the charged lepton is not identified. The data are found to be in good agreement with the expected background. For a Higgs boson mass of 125 GeV, we set a limit at the 95% C.L. on the cross section σ(p¯p →[Z/W]H), assuming standard model branching fractions, that is a factor of 4.3 times larger than the theoretical standard model value, while the expected factor is 3.9. The search is also used to measure a combined W Z and Z Z production cross section that is a factor of 0.94 ± 0.31 (stat) ± 0.34 (syst) times the standard model prediction of 4.4 pb, with an observed significance of 2.0 standard deviations
