We report on a study of the process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}{(D{\overline{D}}^{*})}^{\ensuremath{\mp}}$ at $\sqrt{s}=4.26\text{ }\text{ }\mathrm{GeV}$ using $525\text{ }\mathrm{pb}{}^{\ensuremath{-}1}$ data sample collected with BESIII detector BEPCII storage ring. A distinct charged structure is observed in ${(D{\overline{D}}^{*})}^{\ensuremath{\mp}}$ invariant mass distribution. When fitted to mass-dependent-width...
The branching fraction of the psi(2S) decay into tau pair has been measured for first time using BES detector at Beijing Electron-Positron Collider. result is $B_{\tau\tau}=(2.71\pm 0.43 \pm 0.55) \times 10^{-3}$, where error statistical and second systematic. This value, along with those fractions e+e- mu+mu this resonance, satisfy well relation predicted by sequential lepton hypothesis. Combining all these values leptonic width resonance total determined to be $(252 37)$ keV.
