Evidence for the semileptonic decays $Λ_{c}^{+} \to Σ^{\pm} π^{\mp} e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +680

Using $4.5 f b^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at center-of-mass energies between $4.600$ and $4.699 G e V$ , we search for the semileptonic decays…

Measurement of the $η$ transition form factor through $η^{'} \to π^{+} π^{-} η$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Based on a sample of $(1.0087 \pm 0.0044) \times 1 0^{10}$ $J / ψ$ events collected at BESIII, the transition form factor of the $η$ meson is extracted by analyzing $J/ψ\toγη',~η'\toπ^+π^…
