Radiative Decay of the ψ(2S) into Two Pseudoscalar Mesons

BES Collaboration

Radiative decays of the radially excited charmonium resonance, ψ(2S), into ππ, K Kbar and ηηfinal states have been measured in a sample of 3.96 * 10^6 ψ(2S) events collected by the…

Measurement of $ψ (2 S)$ decays to baryon pairs

J. Z. Bai

A sample of 3.95M $ψ (2 S)$ decays registered in the BES detector are used to study final states containing pairs of octet and decuplet baryons. We report branching fractions for $ψ(…

Partial Wave Analysis of $J / ψ \to γ (K^{\pm} K_{S}^{0} π^{\mp})$

J. Z. Bai

BES data on $J / ψ \to γ (K^{\pm} K_{S}^{0} π^{\mp})$ are presented. There is a strong peak due to $η (1440) / ι$ , which is fitted with a Breit-Wigner amplitude with $s$ -dependent widths for…

Partial Wave Analysis of $J / ψ \to γ (π^{+} π^{-} π^{+} π^{-})$

J. Z. Bai

BES data on $J / ψ \to γ (π^{+} π^{-} π^{+} π^{-})$ have been analyzed into partial waves. We fit with resonances having $J^{P C} = 2^{++}$ at 1275 MeV, $0^{++}$ at 1500 MeV, $2^{++}$ at…

Partial Wave Analysis of $J / ψ \to γ (K^{+} K^{-} π^{+} π^{-})$

J. Z. Bai

BES data on $J / ψ \to γ (K^{+} K^{-} π^{+} π^{-})$ are presented. The $K^{*} K ˉ^{*}$ contribution peaks strongly near threshold. It is fitted with a broad $0^{-+}$ resonance with mass $M = 1800 \…
