Measurements of decays into , , and
M. Ablikim
Based on events collected with BESII at the Beijing Electron-Positron Collider (BEPC), the decay branching fractions of , , and are measur…
Partial Wave Analysis of
M. Ablikim, BES Collaboration
A partial wave analysis of in decay is presented using a sample of 14 million events accumulated by the BES II detector. The data…
Observation of psi(3770)--> pi pi J/psi and Measurement of Gamma_{ee}[psi(2S)]
N. E. Adam, CLEO Collaboration
We observe signals for the decays psi(3770)--> X J/psi from data acquired with the CLEO detector operating at the CESR e^+e^- collider with sqrt{s}=3773 MeV. We measure the followi…
Obervation of χ_{cJ}--> omega omega decays
BES Collaboration, M. Ablikim
Decays of $χ_{c0,2}\ar\ww$ are observed for the first time using a sample of events collected with the BESII detector. The branching ratios are determined…
Study of J/psi decays to Lambda Lambdabar and Sigma0 Sigma0bar
BES Collaboration, M. Ablikim
The branching ratios and Angular distributions for J/psi decays to Lambda Lambdabar and Sigma0 Sigma0bar are measured using BESII 58 million J/psi.
Precise measurement of spin-averaged chi_{cJ}(1P) mass using photon conversions in psi(2S) -> gamma chi_{cJ}
M. Ablikim, J. Z. Bai
Using photon conversions to e^+e^- pairs, the energy spectrum of inclusive photons from psi(2S) radiative decays is measured by BESII at the Beijing Electron-Positron Collider. The…
