Evidence of transverse polarization of $Ξ^{0}$ hyperon in $ψ (3686) \to Ξ^{0} Ξ ˉ^{0}$

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

Using $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, we report an evidence of $Ξ^{0}$ transverse polarization with a sign…

First determination of the full spin density matrix in $ψ (3686) \to Λ Λ ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +688

Using $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector, we present the first complete determination of the spin density matrix in $ψ (3686) \to Λ Λ ˉ$ .…

Measurement of the space-like $π^{0}$ transition form factor

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

Based on $2.93 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at a center-of-mass energy of $3.773 GeV$ , the two-photon fusion process $e^+e^-\t…

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…

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 $D \to K ˉ_{1} (1270) μ^{+} ν_{μ}$ and test of lepton flavor universality with $D \to K ˉ_{1} (1270) ℓ^{+} ν_{ℓ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

By analyzing 7.93 $f b^{- 1}$ of $e^{+} e^{-}$ collision data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report t…
