First observations of $ψ (2 S)$ and $χ_{c J} (1 P)$ decays to four-body final states $h^{+} h^{-} K_{S}^{0} K_{S}^{0}$

M. Ablikim

$χ_{c 0}$ , $χ_{c 1}$ , and $χ_{c 2}$ decays to $π^{+} π^{-} K_{S}^{0} K_{S}^{0}$ and $K^{+} K^{-} K_{S}^{0} K_{S}^{0}$ , as well as $ψ (2 S)$ decay to $π^{+} π^{-} K_{S}^{0} K_{S}^{0}$ are presented. The branching fractions of these…

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…

Search for the Lepton Flavor Violation Processes $J / ψ \to$ $μτ$ and $e τ$

BES collaboration

The lepton flavor violation processes $J / ψ \to μτ$ and $e τ$ are searched for using a sample of 5.8 $\times 1 0^{7}$ $J / ψ$ events collected with the BESII detector. Zero and one candidat…

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 $^{2}$ (…
