Measurements of the branching fractions of the $P$ -wave charmonium spin-singlet state $h_{c} (^{1} P_{1}) \to h^{+} h^{-} π^{0} / η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +649

Based on $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events, we investigate four hadronic decay modes of the $P$ -wave charmonium spin-singlet state $h_{c} (^{1} P_{1}) \to h^{+} h^{-} π^{0} / η$ ($h=…

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…
