Search for a $1^{-+}$ molecular state via $e^{+} e^{-} \to γ D_{s}^{+} D_{s 1}^{-} (2536) + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +651

We search, for the first time, for an exotic molecular state with quantum numbers $J^{P C} = 1^{-+}$ , called $X$ , via the process $e^{+} e^{-} \to γ D_{s}^{+} D_{s 1}^{-} (2536) + c . c .$ us…

Observation of the charmonium decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +662

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the decay $η_{c} \to γ γ$ in $J / ψ \to γ η_{c}$ is observed. We determine the p…

Strong and weak $C P$ tests in sequential decays of polarized $Σ^{0}$ hyperons

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

The $J / ψ, ψ (3686) \to Σ^{0} Σ ˉ^{0}$ processes and subsequent decays are studied using the world's largest $J / ψ$ and $ψ (3686)$ data samples collected with the BESIII detector. The…

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=…

Study of the $h_{c}$ ( $1^{1} P_{1}$ ) meson via $ψ (2 S) \to π^{0} h_{c}$ decays at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +549

Using 448 million $ψ (2 S)$ events, the spin-singlet $P$ -wave charmonium state $h_{c}$ (1 $^{1} P_{1}$ ) is studied via the $ψ (2 S) \to π^{0} h_{c}$ decay followed by the $h_{c} \to γ η_{c}$ tra…
