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 branching fraction and decay asymmetry of $Λ \to nγ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +565

The radiative hyperon decay $Λ \to nγ$ is studied using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector operating at BEPCII. The absolute branching fractio…

Amplitude analysis and branching fraction measurement of the decay $D_{s}^{+} \to K^{+} π^{+} π^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +560

Using $6.32$ fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected at the center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysi…
