Measurement of the Integrated Luminosities of Cross-section Scan Data Samples Around the $ψ (3770)$ Mass Region

M. Ablikim, M. N. Achasov, S. Ahmed +460

To investigate the nature of the $ψ (3770)$ resonance and to measure the cross section for $e^{+} e^{-} \to D D ˉ$ , a cross-section scan data sample, distributed among 41 center-of-ma…

Search for the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi

M. Ablikim, J. Z. Bai

Using 14.0\times 10^6 ψ(2S) events collected with the BES-II detector, the C-parity violating process J/psi->gamma gamma via psi(2S)->pi+pi- J/psi is studied. We determine a new up…

Improved measurement of $ψ (2 S)$ decays into $τ^{+} τ^{-}$

BES Collaboration, M. AblikimJ

Using 14M $ψ (2 S)$ events collected at BESII, the branching fraction of $ψ (2 S) \to τ^{+} τ^{-}$ is measured to be $B r_{τ τ} = (3.10 \pm 0.21 \pm 0.38) \times 1 0^{- 3}$ , where the first error…
