First Direct Measurement of the Absolute Branching Fraction of $Σ^{+} \to Λ e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +591

The first direct measurement of the absolute branching fraction of $Σ^{+} \to Λ e^{+} ν_{e}$ is reported based on an $e^{+} e^{-}$ annihilation sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ eve…

Measurement of the $C P$ -even fraction of $D^{0} \to K^{+} K^{-} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +571

A determination of the $C P$ -even fraction $F_{+}$ in the decay $D^{0} \to K^{+} K^{-} π^{+} π^{-}$ is presented. Using $2.93$ fb $^{- 1}$ of $e^{+} e^{-} \to ψ (3770) \to D D ˉ$ data collected by the B…

Search for an axion-like particle in radiative $J / ψ$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +588

We search for an axion-like particle (ALP) $a$ through the process $ψ (3686) \to π^{+} π^{-} J / ψ$ , $J / ψ \to γ a$ , $a \to γ γ$ in a data sample of $(2.71 \pm 0.01) \times 1 0^{9}$ …
