Cross section measurement of $e^{+} e^{-} \to η^{'} J / ψ$ from $s = 4.178$ to $4.600$ GeV

M. Ablikim, M. N. Achasov, P. Adlarson +477

The cross section of the process $e^{+} e^{-} \to η^{'} J / ψ$ is measured at center-of-mass energies from $s =$ 4.178 to 4.600 GeV using data samples corresponding to a total…

Observation of the leptonic decay $D^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +479

We report the first observation of $D^{+} \to τ^{+} ν_{τ}$ with a significance of $5.1 σ$ . We measure ${\cal B}(D^+\toτ^+ν_τ) = (1.20\pm0.24_{\text{stat.}}\pm0.12_{\text{syst.}})\times10^{-3…

Measurement of the branching fraction of $J / ψ \to ω η^{'} π^{+} π^{-}$ and search for $J / ψ \to ω X (1835), X (1835) \to η^{'} π^{+} π^{-}$ decay

BESIII Collaboration

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected by the BESIII detector at BEPCII during 2009 and 2012, we study the $J / ψ \to ω η^{'} π^{+} π^{-}$ hadronic process.…

Using a total of $9.0 fb^{- 1}$ of $e^{+} e^{-}$ collision data with center-of-mass energies between 4.15 and 4.30 GeV collected by the BESIII detector, we search for the proces…
