Measurement of the absolute branching fraction for $Λ_{c}^{+} \to Λ e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +65

We report the first absolute measurement of the branching fraction of $Λ_{c}^{+} \to Λ e^{+} ν_{e}$ . This measurement is based on 567 pb $^{- 1}$ of $e^{+} e^{-}$ annihilation data produce…

Measurement of the $e^{+} e^{-} \to π^{+} π^{-}$ Cross Section between 600 and 900 MeV Using Initial State Radiation

M. Ablikim, M. N. Achasov, X. C. Ai +398

We extract the $e^{+} e^{-} \to π^{+} π^{-}$ cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated…

Measurement of the branching fractions of $D_{s}^{+} \to η^{'} X$ and $D_{s}^{+} \to η^{'} ρ^{+}$ in $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +414

We study $D_{s}^{+}$ decays to final states involving the $η^{'}$ with a 482pb $^{- 1}$ data sample collected at $s$ = 4.009GeV with the \mbox{BESIII} detector at the BEP…
