Measurement of the branching fraction of $D_{s}^{+} \to ℓ^{+} ν_{ℓ}$ via $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

Based on $10.64 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken at center-of-mass energies between 4.237 and 4.699 GeV with the BESIII detector, we study the leptonic $D_{s}^{+}$ de…

Measurements of Normalized Differential Cross Sections of Inclusive $η$ Production in $e^{+} e^{-}$ Annihilation at Energy from 2.0000 to 3.6710 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using data samples collected with the BESIII detector operating at the BEPCII storage ring, the cross section of the inclusive process $e^{+} e^{-} \to η + X$ , normalized by the tota…

Updated measurements of the M1 transition $ψ (3686) \to γ η_{c} (2 S)$ with $η_{c} (2 S) \to K K ˉ π$

BESIII Collaboration, M. Ablikim, M. N. Achasov +620

Based on a data sample of $(27.08 \pm 0.14) \times 1 0^{8} ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the M1 transition $ψ (3686) \to γ η_{c} (2 S)$ with…

Observation of the Singly Cabibbo-Suppressed Decay $Λ_{c}^{+} \to Σ^{-} K^{+} π^{+}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +616

The singly Cabibbo-suppressed decay $Λ_{c}^{+} \to Σ^{-} K^{+} π^{+}$ is observed for the first time with a statistical significance of $6.4 σ$ by using 4.5 fb $^{- 1}$ of $e^{+} e^{-}$ colli…
