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…

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

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 $J / I ¨ \to e^{+} e^{-} I ¨ ^{0}$ using $(10087 \pm 44) \…

Measurement of Branching Fractions for $I^_{c}^{+} \to n K_{S}^{0} I ¨ ^{+}$ and $I^_{c}^{+} \to n K_{S}^{0} K^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +611

Based on 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ collision data accumulated at center-of-mass energies between $4.600 GeV$ and $4.699 GeV$ with the BESIII detector, we me…

Measurements of the branching fractions of semileptonic $D_{s}^{+}$ decays via $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

We measure the absolute branching fractions of semileptonic $D_{s}^{+}$ decays via the $e^{+} e^{-} \to D_{s}^{*+} D_{s}^{*-}$ process using $e^{+} e^{-}$ collision data corresponding to an integrated…
