Exploring the intrinsic energy resolution of liquid scintillator to approximately 1 MeV electrons
Y. Deng, X. Sun, B. Qi +22
We proposed a novel method for exploring the intrinsic energy resolution of a liquid scintillator (LAB + 2.5 g/L PPO + 3 mg/L bis-MSB) for approximately 1 MeV electrons. With the h…
Partial wave analyses of J/psi to gamma pi^+ pi^- and gamma pi^0 pi^0
M. Ablikim
Results are presented on J/psi radiative decays to pi^+pi^- and pi^0pi^0 based on a sample of 58M J/psi events taken with the BESII detector. Partial wave analyses are carried out…
BESII Detector Simulation
BES Collaboration
A Monte Carlo program based on Geant3 has been developed for BESII detector simulation. The organization of the program is outlined, and the digitization procedure for simulating t…

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…
A Measurement of Psi(2S) Resonance Parameters
BES Collaboration, J. Z. Bai
Cross sections for e+e- to hadons, pi+pi- J/Psi, and mu+mu- have been measured in the vicinity of the Psi(2S) resonance using the BESII detector operated at the BEPC. The Psi(2S) t…
First Measurement of the Branching Fraction of the Decay psi(2S) --> tau tau
J. Z. Bai
The branching fraction of the psi(2S) decay into tau pair has been measured for the first time using the BES detector at the Beijing Electron-Positron Collider. The result is $B_{τ…
Determination of the J/psi Leptonic Branching Fraction via psi(2S) -> pi^+ pi^- J/psi
J. Z. Bai
A comparison of the rates for psi(2S) -> pi^+ pi^- J/psi, J/psi -> l^+l^- and J/psi -> anything is used to determine the J/psi leptonic branching fractions. The results are B(J/psi…
