Measurements of absolute branching fractions of $D^{0 (+)} \to K K K π$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +697

Using an $e^{+} e^{-}$ sample of $20.3 f b^{- 1}$ collected at the center-of-mass energy $s =$ 3.773 GeV with the BESIII detector, we report measurements of several four-body h…

First observation of quantum correlations in $e^{+} e^{-} \to X D D ˉ$ and $C$ -even constrained $D D ˉ$ pairs

BESIII Collaboration, M. Ablikim, M. N. Achasov +698

The study of meson pairs produced with quantum correlations gives direct access to parameters that are challenging to measure in other systems. In this Letter, the existence of qua…

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…

Cross section measurement of $e^{+} e^{-} \to f_{1} (1285) π^{+} π^{-}$ at center-of-mass energies between $3.808$ and $4.951 GeV$

BESIII Collaboration, M. Ablikim, M. N. Achasov +644

Using data samples collected by the \mbox{BESIII} detector located at the Beijing Electron Positron Collider, the cross sections of the process $e^{+} e^{-} \to f_{1} (1285) π^{+} π^{-}$ are me…

Study of $η \to π^{+} π^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events accumulated with the BESIII detector, we analyze the decays $η \to π^{+} π^{-} l^{+} l^{-}$ ( $l = e$ or $μ$ ) via the process $J/ψ…
