Improved measurement of the branching fractions for $J / ψ \to γ π^{0}$ , $γ η$ and $γ η^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +609

Using a data sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected with the BESIII detector, the decays of $J / ψ \to γ π^{0} (η, η^{'}) \to γ γ γ$ are studied. Newly measu…

Determination of spin and parity of $D_{(s)}^{*}$ mesons

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

The spin and parity of the charmed mesons $D_{s}^{*+}$ , $D^{* 0}$ and $D^{*+}$ are determined for the first time to be $J^{P} = 1^{-}$ with significances greater than 10 $σ$ over other h…

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…
