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

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

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

Test of $C P$ Symmetry in the Neutral Decays of $I^$ via $J / I ¨ \to I^ I^ˉ $

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

Using $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events collected with the BESIII detector, a full angular distribution analysis is carried out on the process $J/Ï\rightarrowÎ\barÎ\right…
