Precision measurements of branching fractions for $ψ^{'} \to π^{0} J ψ$ and $η J ψ$

M. Ablikim, M. N. Achasov, O. Albayrak +342

We present a precision study of the $\psip\toπ^0 J/ψ$ and $η J / ψ$ decay modes. The measurements are obtained using $106 \times 1 0^{6}$ $ψ^{'}$ events accumulated with the BESIII detector a…

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…

Measurements of $ψ (2 S)$ decays into Vector- Tensor final states

J. Z. Bai et al

Decays of the $ψ (2 S)$ into vector plus tensor meson final states have been studied with 14 million $ψ (2 S)$ events collected with the BESII detector. Branching fractions of $ψ(2S) \…

Direct Measurement of B(D0->phiX0) and B(D+->phiX+)

BES Collaboration, J. Z. Bai

The first measurement of B(0->phi X0) and an upper limit for B(D+->phi X+) are determined from 22.3 pb-1 of e+e- annihilation data at a C. M. energy of 4.03 GeV. The data were reco…

Charmonium Decays to Axialvector plus Pseudoscalar Mesons

BES Collaboration, J. Z. Bai

A sample of 3.79 million psi(2S) decays observed in the BES detector is used to study the decays of charmonium to axialvector plus pseudoscalar mesons. The branching fraction for p…
