BES data on J/ψ → γ(KKππ) are presented. The KK̄ contribution peaks strongly near threshold. It is fitted with a broad 0 resonance with mass M = 1800 ± 100 MeV, width Γ = 500 ± 200 MeV. A broad 2 resonance peaking at 2020 MeV is also required with width ∼ 500 MeV. There is further evidence for a 2 component peaking at 2.55 GeV. The non-KK̄ contribution is… (More)

Liver X receptors (LXRs) are important transcriptional regulators of lipid homeostasis and proliferation in several cell types. However, the roles of LXRs in pancreatic beta cells have not been fully established. The aim of this study was to investigate the effects of LXRs on pancreatic beta cell proliferation. Gene expression was analysed using real-time… (More)

The Rayleigh-Stokes problem for a generalized Maxwell fluid in a porous half-space with a heated flat plate is investigated. For the description of such a viscoelastic fluid, a fractional calculus approach in the constitutive relationship model is used. By using the Fourier sine transform and the fractional Laplace transform, exact solutions of the velocity… (More)

The decay J/ψ → ωpp̄ is studied using a 5.8 × 10 J/ψ event sample accumulated with the BES II detector at the Beijing electron-positron collider. The decay branching fraction is measured to be B(J/ψ → ωpp̄) = (9.8 ± 0.3 ± 1.4) × 10. No significant enhancement near the pp̄ mass threshold is observed, and an upper limit of B(J/ψ → ωX(1860))B(X(1860) → pp̄)<… (More)

The processes ψ(2S) → γπ+π−, γK+K− and γpp̄ have been studied using a sample of 3.79 × 106 ψ(2S) decays. We determine the total width of the χc0 to be Γ tot χc0 = 14.3 ± 2.0 ± 3.0 MeV. We present the first measurement of the branching fraction B(χc0 → pp̄) = (15.9 ± 4.3 ± 5.3) × 10−5, where the first error is statistical and the second one systematic.… (More)

A partial wave analysis is presented of J/ψ → φππ and φKK from a sample of 58M J/ψ events in the BES II detector. The f0(980) is observed clearly in both sets of data, and parameters of the Flatté formula are determined accurately:M = 965± 8 (stat) ±6 (syst) MeV/c, g1 = 165± 10± 15 MeV/c, g2/g1 = 4.21± 0.25± 0.21. The φππ data also exhibit a strong ππ peak… (More)

Using 14 million ψ(2S) events collected with the BESII detector, branching fractions of ψ(2S) → K(892)K+c.c. and K(892)K 0 + c.c. are determined to be: B(ψ(2S) → K(892)K + c.c.) = (2.9 −1.7 ± 0.4) × 10 −5 and B(ψ(2S) → K(892)K 0 + c.c.) = (13.3 −2.7 ± 1.7)× 10 . The results confirm the violation of the “12% rule” for these two decay channels. A large… (More)
