Measurements of the branching fractions of semileptonic $D_{s}^{+}$ decays via $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

We measure the absolute branching fractions of semileptonic $D_{s}^{+}$ decays via the $e^{+} e^{-} \to D_{s}^{*+} D_{s}^{*-}$ process using $e^{+} e^{-}$ collision data corresponding to an integrated…

Precison Measurements of the Mass, the Widths of $ψ (3770)$ Resonance and the Cross Section $σ [e^{+} e^{-} \to ψ (3770)]$ at $E_{cm} = 3.7724$ GeV

M. Ablikim et al.

By analyzing the $R$ values measured at 68 energy points in the energy region between 3.650 and 3.872 GeV reported in our previous paper, we have precisely measured the mass, the t…

Direct measurement of the absolute branching fraction for $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ and determination of $Γ (D^{0} \to K^{-} μ^{+} ν_{μ}) /Γ (D^{+} \to K ˉ^{0} μ^{+} ν_{μ})$

M. Ablikim

The absolute branching fraction for the decay $D^{+} \to K ˉ^{0} μ^{+} ν_{μ}$ is determined using $5321 \pm 149 \pm 160$ singly tagged $D^{-}$ sample from the data collected around 3.773 G…

Measurements of $\psip$ decays into $γ K K ˉ π$ and $γη\pipi$

M. Ablikim

Radiative decays of the $\psip$ into $γ K K ˉ π$ and $γη\pipi$ final states are studied using 14 million $\psip$ events collected with the BESII detector. Branching fractions or u…

Measurements of the cross sections for $e^{+} e^{-} \to hadrons$ at 3.650, 3.6648, 3.773 GeV and the branching fraction for $ψ (3770) \to non - D D ˉ$

M. Ablikim et al.

Using the BES-II detector at the BEPC Collider, we measured the lowest order cross sections and the $R$ values ( $R = σ_{e^{+} e^{-} \to hadrons}^{0} / σ_{e^{+} e^{-} \to μ^{+} μ^{-}}^{0}$ ) for incl…
