Using 14.0 million \jpsi\psipto\jpsi$ peak i…
Precison Measurements of the Mass, the Widths of Resonance and the Cross Section at GeV
M. Ablikim et al.
By analyzing the values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…
Direct measurement of the absolute branching fraction for and determination of
M. Ablikim
The absolute branching fraction for the decay is determined using singly tagged sample from the data collected around 3.773 G…
Measurements of $\psip$ decays into and $γη\pipi$
M. Ablikim
Radiative decays of the $\psip$ into and $γη\pipi$ final states are studied using 14 million $\psip$ events collected with the BESII detector. Branching fractions or u…
