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…

Precision measurement of the branching fraction for the decay $ψ (2 S) \to τ^{+} τ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +684

Using $(2259.3 \pm 11.1) \times 1 0^{6}$ $ψ (2 S)$ events acquired with the BESIII detector, the branching fraction of $ψ (2 S) \to τ^{+} τ^{-}$ is measured with improved precision t…
