Observation of a resonance X(1835) in J/ψ--> γπ^+ π^- η^{\prime}

BES Collaboration, M. Ablikim

The decay channel J/ψ--> γπ^+ π^- η^{\prime} is analyzed using a sample of 5.8\times 10^7 Jψevents collected with the BESII detector. A resonance, the X(1835), is observed in the π…

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…

Improved measurement of the branching ratio of J/psi-->K_S K_L

J. Z. Bai

The branching ratio of J/psi-->K_S K_L is measured with improved precision to be B(J/psi-->K_S K_L) = (1.82\pm 0.04\pm 0.13)\times 10^{-4}. using J/psi data collected with the Beij…
