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…

Measurement of the Branching Fraction for the Decay $ψ (3686) \to ϕ K_{S}^{0} K_{S}^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +592

Based on $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay $ψ (3686) \to ϕ K_{S}^{0} K_{S}^{0}$ is…

First Direct Measurement of the Absolute Branching Fraction of $Σ^{+} \to Λ e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +591

The first direct measurement of the absolute branching fraction of $Σ^{+} \to Λ e^{+} ν_{e}$ is reported based on an $e^{+} e^{-}$ annihilation sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ eve…
