Direct Measurement of the Pseudoscalar Decay Constant fD+

BES Collaboration

The absolute branching fraction of $D^{+} \to μ^{+} ν$ has been directly measured by an analysis of a data sample of about 33 $p b^{- 1}$ collected around $s = 3.773$ GeV with…

The $σ$ pole in $J / ψ \to ω π^{+} π^{-}$

BES Collaboration

Using a sample of 58 million $J / ψ$ events recorded in the BESII detector, the decay $J / ψ \to ω π^{+} π^{-}$ is studied. There are conspicuous $ω f_{2} (1270)$ and $b_{1} (1235) π$ signals. At lo…

A Study of J/psi-->gamma gamma V(rho,phi) Decays with the BESII Detector

BES Collaboration

Using a sample of $58 \times 1 0^{6}$ $J / ψ$ events collected with the BESII detector, radiative decays $J / ψ \to γ γ V$ , where $V = ρ$ or $ϕ$ , are studied. A resonance around 1420 MeV/c $^{2}$ (…
