Search for $η_{1} (1855)$ in $χ_{c J} \to η η η^{'}$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Based on a sample of $2.7 \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, an analysis of the decay $ψ(3686)\toγχ_{cJ}, χ_{cJ}\toηηη…

Observation of the decay $ψ (3686) \to Σ^{0} Σ ˉ^{0} ω$

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Using a dataset of $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the first observation of the decay $…

Analysis of the dynamics of the decay $D^{+} \to K_{S}^{0} π^{0} e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +649

The branching fraction of $D^{+} \to K_{S}^{0} π^{0} e^{+} ν_{e}$ is measured for the first time using $7.93 fb^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at the center-of-mass…
