Search for the semileptonic decays $D_{s}^{+} \to K_{1} (1270)^{0} e^{+} ν_{e}$ and $D_{s}^{+} \to b_{1} (1235)^{0} e^{+} ν_{e}$

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

By analyzing 7.33\,fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we search for the semileptonic de…

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…
