Measurements of the branching fractions of $χ_{c J} \to ϕϕ η, ϕϕ η^{'}$ and $ϕ K^{+} K^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +683

Using a sample of $(2712.4 \pm 14.3) \times 1 0^{6} ψ$ (3686) events collected by the BESIII detector at the BEPCII collider, we measure the branching fractions of the decays $χ_{cJ}\t…

First Experimental Study of the Purely Leptonic Decay $D_{s}^{*+} \to e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using $7.33 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at the BEPCII collider, we report the first experimental study of the purely leptonic decay…

Search for the weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

The Cabibbo-allowed weak radiative decay $Λ_{c}^{+} \to Σ^{+} γ$ has been searched for in a sample of $Λ_{c}^{+} Λ ˉ_{c}^{-}$ pairs produced in $e^{+} e^{-}$ annihilations, corresponding to an i…
