Observation of a New Excited $Σ$ State in $ψ (3686) \to p ˉ K^{+} Σ^{0} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +681

Using a data sample of $(2712.4 \pm 14.3) \times 1 0^{6} ψ (3686)$ events collected with the BESIII detector, a partial-wave analysis of $ψ (3686) \to p ˉ K^{+} Σ^{0} + c . c .$ is performed. A new…

Measurements of the branching fractions of $ψ (3686) \to Σ ˉ^{0} Λ + c . c .$ and $χ_{c J (J = 0, 1, 2)} \to Λ Λ ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +505

Based on $4.481 \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector at BEPCII, the branching fraction of the isospin violating decay $ψ (3686) \to Σ ˉ^{0} Λ + c . c .$ …

Search for the decay $η^{'} \to γ γ η$

M. Ablikim, M. N. Achasov, P. Adlarson +479

Using a data sample of $1.31 \times 1 0^{9} J / ψ$ events collected with the BESIII detector, a search for $η^{'} \to γ γ η$ via $J / ψ \to γ η^{'}$ is performed for the first time. No significant $η…
