Observation of $e^{+} e^{-} \to D_{s}^{+} D^{(*) 0} K^{-}$ and study of the $P$ -wave $D_{s}$ mesons

BESIII Collaboration, M. Ablikim, M. N. Achasov +453

Studies of $e^{+} e^{-} \to D_{s}^{+} D^{(*) 0} K^{-}$ and the $P$ -wave charmed-strange mesons are performed based on an $e^{+} e^{-}$ collision data sample corresponding to an integrat…

Measurement of the absolute branching fractions of $Λ_{c}^{+} \to Λ η π^{+}$ and $Σ (1385)^{+} η$

M. Ablikim, M. N. Achasov, S. Ahmed +447

We study the decays $Λ_{c}^{+} \to Λ η π^{+}$ and $Σ (1385)^{+} η$ based on $Λ_{c}^{+} Λ ˉ_{c}^{-}$ pairs produced in $e^{+} e^{-}$ collisions at a center-of-mass energy of $\sqrt{s}=4.6~\mb…

Evidence for the decays of $Λ_{c}^{+} \to Σ^{+} η$ and $Σ^{+} η^{'}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +458

We study the hadronic decays of $Λ_{c}^{+}$ to the final states $Σ^{+} η$ and $Σ^{+} η^{'}$ , using an $e^{+} e^{-}$ annihilation data sample of 567 pb $^{- 1}$ taken at a center-of-mas…

First observations of $h_{c} \to$ hadrons

M. Ablikim, M. N. Achasov, S. Ahmed +461

Based on $(4.48 \pm 0.03) \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector, five $h_{c}$ hadronic decays are searched for via process $ψ (3686) \to π^{0} h_{c}$ . Three o…
