Search for the lepton number violating process $Ξ^{-} \to Σ^{+} e^{-} e^{-} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +691

We present a search for the lepton number violating decay $Ξ^{-} \to Σ^{+} e^{-} e^{-} + c . c .$ with $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected by the BESIII detector at the BEPCII…

Test of $C P$ Symmetry in the Neutral Decays of $Λ$ via $J / ψ \to Λ Λ ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, a full angular distribution analysis is carried out on the process $J/ψ\rightarrowΛ\barΛ\rightarro…
