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…

Precision measurement of the branching fractions of $η^{'}$ decays

M. Ablikim, M. N. Achasov, S. Ahmed +460

Based on a sample of $(1310.6 \pm 7.0) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we present measurements of $J / ψ$ and $η^{'}$ absolute branching fractions usin…

Complete measurement of $Λ$ electromagnetic form factors

M. Ablikim, M. N. Achasov, P. Adlarson +475

The exclusive process $e^{+} e^{-} \to Λ Λ ˉ$ , with $Λ \to p π^{-}$ and $Λ ˉ \to p ˉ π^{+}$ , has been studied at $s =$ 2.396 GeV for measurement of the $Λ$ electric and mag…

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.…
