A wavelet method to the solution for time-fractional partial differential equation, by which combining with Haar wavelet and operational matrix to discretize the given functions efficaciously. The time-fractional partial differential equation is transformed into matrix equation. Then they can be solved in the computer oriented methods. The numerical example(More)
We perform a combination of searches for standard model Higgs boson production in p¯ p collisions recorded by the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of √ s = 1.96 TeV. The different production and decay channels have been analyzed separately, with integrated luminosities of up to 9.7 fb −1 and for Higgs boson masses 90(More)
We present an improved determination of the total width of the top quark, Γt, using 5.4 fb −1 of integrated luminosity collected by the D0 Collaboration at the Tevatron p¯ p Collider. The total width Γt is extracted from the partial decay width Γ(t → W b) and the branching fraction B(t → W b). Γ(t → W b) is obtained from the t-channel single top quark(More)
We present a simultaneous measurement of the forward-backward asymmetry and the top-quark polarization in t ¯ t production in dilepton final states using 9.7 fb −1 of proton-antiproton collisions at ffiffi ffi s p ¼ 1.96 TeV with the D0 detector. To reconstruct the distributions of kinematic observables we employ a matrix element technique that calculates(More)
