Observation of $η_{c} (2 S) \to K^{+} K^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

By analyzing $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (3686)$ events accumulated with the BESIII detector, the decay $η_{c} (2 S) \to K^{+} K^{-} η$ is observed for the first time with a sig…

Observation of two new $N^{*}$ resonances in $ψ (3686) \to p p ˉ π^{0}$

BESIII Collaboration

Based on 106 $\times 1 0^{6} ψ (3686)$ events collected with the BESIII detector at the BEPCII facility, a partial wave analysis of $ψ (3686) \to p p ˉ π^{0}$ is performed. The bra…

Spin-Parity Analysis of ppbar Mass Threshold Structure in J/psi and psi' Radiative Decays

BESIII Collaboration

A partial wave analysis of the $p p ˉ$ mass-threshold enhancement in the reaction $J / ψ \to γ p p ˉ$ is used to determine: its $J^{P C}$ quantum numbers to be $0^{-+}$ ; i…
