Precision Measurement of $D_{s}^{*+}$ - $D_{s}^{+}$ Mass Difference

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

We measure the mass difference between $D_{s}^{*+}$ and $D_{s}^{+}$ , $Δ m_{s}$ , using the decay chain $D_{s}^{*+} \to D_{s}^{+} (\to K^{+} K^{-} π^{+}) π^{0}$ , utilizing $e^{+} e^{-}$ annihi…

Evidence of doubly OZI-suppressed decay $η_{c} \to ω ϕ$ in the radiative decay $J / ψ \to γ η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector at the BEPCII collider, the first evidence for the doubly OZI-suppressed decay $η_{c}…
