Measurement of the $e^{+} e^{-} \to K^{+} K^{-} ψ (2 S)$ Cross Section at Center-of-Mass Energies from 4.699 to 4.951 GeV and Search for $Z_{cs}^{\pm}$ in the $Z_{cs}^{\pm} \to K^{\pm} ψ (2 S)$ Decay

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

We perform the first investigation of the process $e^{+} e^{-} \to K^{+} K^{-} ψ (2 S)$ and report its Born cross sections over a range of center-of-mass energies from 4.699 to 4.951~GeV. Th…

Test of $C P$ Symmetry in Hyperon to Neutron Decays

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

The quantum entangled $J / ψ \to Σ^{+} Σ ˉ^{-}$ pairs from $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events taken by the BESIII detector are used to study the non-leptonic two-body weak…

Observation of the decay $D_{s}^{+} \to ω π^{+} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +571

Using 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at center-of-mass energies between 4.128 and 4.226~GeV, we observe for the first time the decay $D^…
