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…

Observation of the semi-muonic decay $D^{+} \to ω μ^{+} ν_{μ}$

BESIII Collaboration

We report the first observation of the semi-muonic decay $D^{+} \to ω μ^{+} ν_{μ}$ using an $e^{+} e^{-}$ collision data sample corresponding to an integrated luminosity of $2.93~\mathrm{fb}^{-1…

Study of $J / ψ \to ω K^{+} K^{-}$

M. Ablikim

New data are presented on $J / ψ \to ω K^{+} K^{-}$ from a sample of 58M $J / ψ$ events in the upgraded BES II detector at the BEPC. There is a conspicuous signal for $f_{0} (1710) \to K^{+} K^{-}$ a…

Evidence for f0(980)f0(980) production in chi_c0 decays

BES Collaboration, M. Ablikim

Using a sample of 14 million $ψ (2 S)$ events accumulated with the BES II detector, evidence for $f_{0} (980) f_{0} (980)$ production in $χ_{c 0}$ decays is obtained for the first time; the…
