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…

A Measurement of the Mass and Full-Width of the $η_{c}$ Meson

J. Z. Bai

In a sample of 7.8 million $J / ψ$ decays collected in the Beijing Spectrometer, the process J/ $ψ \to γ η_{c}$ is observed for five different $η_{c}$ decay channels: $K^{+} K^{-} π^{+} π^{-}$ , $π^+π^-…
