Search for the charged lepton flavour violating decay $η^{'} \to e μ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Based on $(8998 \pm 40) \times 1 0^{6}$ $J / ψ$ events collected in $e^{+} e^{-}$ collisions at $s = 3.097$ GeV with the BESIII detector, we present a search for the charged lepton flavou…

Study of $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events accumulated with the BESIII detector, we analyze the decays $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$ ( $l = e$ or $I^¼$ ) via the process…
