This paper aims at effectively predicting the dynamic network traffic flow based on quantum-behaved particle swarm optimization algorithm. Firstly, the dynamic network traffic flow prediction problem is analyzed through formal description. Secondly, the structure of the network traffic flow prediction model is given. In this structure, Users can used a… (More)

With help of the recent developments in the heavy quarkonium physics, we reexamine the long distance(LD) effects in B → Xsee dominantly from the charmonium resonances J/Ψ and Ψ′ through the decay chains B → XsJ/Ψ(Ψ) → Xsee. We find that the resonance to nonresonance interference are reduced substantially. Email: duds@bepc3.ihep.ac.cn,… (More)

We discuss the nonfactorization effects in B → J/Ψ + Xs, which is similar to the nonperturbative effect found by Voloshin in the decay B → γ+Xs. The QCD sum rule has been used to estimate the hadron matrix elements. We find that the correction from this effect is very large and the large discrepancy between the theory and the experimental data can be… (More)

The spectrum of the 0++, 0−−, 1−+ and 1+− heavy-light hybrids have been calculated in HQET. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x), gq̄γαγ5G a αμT hv (x) and gq̄σμαG a αμT hv (x). Some strong couplings and decay widths of the heavy-light hybrids to B(D)π are calculated by using the QCD sum rules. The mass of 0++ hybrid with… (More)

The 0 glueball mass is analyzed in the QCD sum rules. We show that in order to determine the 0 glueball mass by using the QCD sum rules method, it is necessary to clarify the following three ingredients: (1) to choose the appropriate moment with acceptable parameters which satisfy all of the criteria; (2) to take account into the radiative corrections; (3)… (More)

We examine the mixing between the sigma meson σ and the ”pure” glueball field H and study the decays of the scalar glueball candidate f0(1500) (a linear combination of σ and H) into two and four pions in effective linear sigma model. From recent experimental data on f0(1500) decay to pions we point out that the mixing angle is of order of 0.1. PACS numbers… (More)

The decay widths of the 0++ and 1−+ heavy-light hybrids to B(D) and pion are calculated by using the QCD sum rules. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x). In order to simplify the calculation and avoid the ambiguity of three-point correlation function, a two-point correlation function between the pion and vacuum is used… (More)

The decay widths of the 0++ and 1−+ heavy-light hybrids to B(D) and pion are calculated by using the QCD sum rules. The interpolated current of the hybrid is chosen as gq̄γαG a αμT hv (x). In order to avoid the infrared problem, a two point correlation function between the pion and vacuum instead of the three point correlation function between the vacuum is… (More)

We discuss the rescattering effects in decays B → π +K. The picture we take is very simple: first, B decay into K ∗ ρ, then K∗ and ρ go to kaon and pion by exchanging a pion. We find a up to ten percent CP violation asymmetry rate. We also discuss its correction to the constraint of angle γ proposed recently. PACS numbers 13.25.Hw 12.28.Lg Email:… (More)

With respect to large samples of Bc mesons expected to be produced at CERN Large Hadron Collider(LHC) and the large branching ratios Br(Bc → τ ν̄) and Br(Bc → μν̄), we suggest that Bc purely leptonic decays could offer an unique probe of the standard model and its extensions such as two Higgs doublet models and models involving supersymmetry, and also the… (More)
