Search for the rare decay $J / ψ \to γ D^{0} + c . c .$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $(10087 \pm 44) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we search for the rare decay $J / ψ \to γ D^{0} + c . c .$ for the first time. No obvious signal is observed and t…

Amplitude analysis and branching fraction measurement of the decay $D^{+} \to K_{S}^{0} π^{+} π^{0} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +612

Using 2.93 $fb^{- 1}$ of $e^{+} e^{-}$ collision data collected with the BESIII detector at the center-of-mass energy 3.773\,GeV, we perform the first amplitude analysis of the deca…

First Experimental Study of the Purely Leptonic Decay $D_{s}^{*+} \to e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using $7.33 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at the BEPCII collider, we report the first experimental study of the purely leptonic decay…
