New data are presented on $J/ψ\to ωK^+K^-$ from a sample of 58M $J/ψ$ events in the upgraded BES II detector at BEPC. There is conspicuous signal for $f_0(1710) \to K^+K^-$ and peak higher mass which may be fitted with $f_2(2150) K\bar K$. From combined analysis $ωπ^+ π^-$ data, branching ratio $BR(f_0(1710)\toππ)/BR(f_0(1710) K)$ $< 0.11$ 95% confidence level.
Using 58$\times 10^{6}$ $\jpsi$ events collected with the Beijing Spectrometer (BESII) at Electron Positron Collider (BEPC), branching fractions of to $p\bar{p}\eta$ and $p\bar{p}\etap$ are determined. The ratio $\frac{\Gamma(\jpsi\rar\ppb\eta)}{\Gamma(\jpsi\rar\ppb)}$ obtained by this analysis agrees expectations based on soft-pion theorem calculations.
In this paper, we consider the networks modeled by several self-affine sets based on Bedford–Mcmullen carpet. We calculate three properties of networks, including cumulative degree distribution, average clustering coefficient and path length. show that such have scale-free small-world effects.
In this paper, we extend the results for connectivity and convex hulls of Sierpiński relatives whose have right isosceles triangle boundaries to corresponding equilateral version. Furthermore, use a particular subclass called trapezoid-shaped build new hexagonal fractals, which helps visualize distinguish subgroups symmetries hexagon. These contribute identify topologies relatives.
