Observation of Transverse Polarization and Determination of Psionic Form Factors of the $Λ$ Hyperon at $s = 3.773$ GeV

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

Using a data sample of $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 20.3 fb $^{- 1}$ collected by the BESIII detector at the BEPCII collider, we present a…

Observation of the charmonium decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +662

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$ is observed. We determine the p…

Search for the massless dark photon with $D^{0} \to ω γ^{'}$ and $D^{0} \to γ γ^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +653

Using $7.9 f b^{- 1}$ of $e^{+} e^{-}$ collision data collected at $s = 3.773$ GeV with the BESIII detector at the BEPCII collider, we search for the massless dark photon with t…
