Test of local realism via entangled $Λ Λ ˉ$ system

BESIII Collaboration, M. Ablikim, M. N. Achasov +608

The non-locality of quantum correlations is a fundamental feature of quantum theory. The Bell inequality serves as a benchmark for distinguishing between predictions made by quantu…

Measurement of the Inclusive Cross Sections of Prompt $J / ψ$ and $ψ (3686)$ Production in $e^{+} e^{-}$ Annihilation from $s = 3.808$ to $4.951$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The inclusive cross sections of prompt $J / ψ$ and $ψ (3686)$ production are measured at center-of-mass energies from 3.808 to 4.951 GeV. The dataset used is 22 fb $^{- 1}$ of $e^{+}e^{…

Observation of the Electromagnetic Dalitz Transition $h_{c} \to e^{+} e^{-} η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +504

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ decays and data samples of $e^{+} e^{-}$ collisions with $s$ from 4.130 to 4.780~GeV collected with the BESIII detector, we report the…

Precision measurement of the branching fraction of \boldmath $J / ψ \to K^{+} K^{-}$ via $ψ (2 S) \to π^{+} π^{-} J / ψ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $448.1 \times 1 0^{6}$ $ψ (2 S)$ events collected with the BESIII detector, we perform a study of the decay $J / ψ \to K^{+} K^{-}$ via $ψ (2 S) \to π^{+} π^{-} J / ψ$ . T…

Search for the leptonic decays $D^{+} \to e^{+} ν_{e}$ and $D^{+} \to μ^{+} ν_{μ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +572

We present the first search for the leptonic decays $D^{*+} \to e^{+} ν_{e}$ and $D^{*+} \to μ^{+} ν_{μ}$ by analyzing a data sample of electron-positron collisions recorded with the BESIII de…
