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…

Search for the massless dark photon with $D^0\toÏÎ³'$ and $D^0\toÎ³Î³'$

BESIII Collaboration, M. Ablikim, M. N. Achasov +653

Using $7.9 f b^{- 1}$ of $e^{+} e^{-}$ collision data collected at $s = 3.773$ GeV with the BESIII detector at the BEPCII collider, we search for the massless dark photon with t…
