Using a sample of 58 million J/ψ events recorded in the BESII detector, the decay J/ψ → ωπ+π− is studied. There are conspicuous ωf2(1270) and b1(1235)π signals. At low ππ mass, a large broad peak due to the σ is observed, and its pole position is determined to be (541 ± 39) i (252 ± 42) MeV from the mean of six analyses. The errors are dominated by the systematic errors. PACS: 13.25.Gv, 14.40.G...

Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement for the Cabibbo-suppressed decay modeD0 → K+K−π+π−. We measure: Γ(D0 → K+K−π+π−)/Γ(D0 → K−π−π+π+) = 0.0295 ± 0.0011 ± 0.0008 . An amplitude analysis has been performed in order to determine the resonant substructure of this decay mode. The dominant components are the decays D0 → K1(1270) +K−, D0 → K1(1400) +K−...

Twelve well-characterized activated carbons with average micropore widths between 0.7 and 2 nm, total surface areas of 378–1270 m2 g−1 and specific capacitances C up to 320 F g−1 have been investigated, using H2SO4 2 M as electrolyte. Some of the carbons have also been oxidized with (NH4)2S2O8, which leads to specific oxygen contents between 0.4 and 7.1 mol m−2 of carbon surface area. It appear...
