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…
