Measurements of the absolute branching fractions of $Ω^{-}$ decays and test of the $Δ I = 1/2$ rule

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

Based on a data set of $(27.12 \pm 0.10) \times 1 0^{8}$ $ψ (3686)$ events collected at the BESIII experiment, the absolute branching fractions of the three dominant $Ω^{-}$ decays are meas…

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…
