Study of $η \to π^{+} π^{-} l^{+} l^{-}$

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

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

Study of the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

We report the first measurement of the di-electron invariant mass dependent transition form factor in the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} π^{0}$ using $(10087 \pm 44) \ti…
