Based on $(10.09 \pm 0.04) \times 10^9$ $J/ψ$ events collected with the BESIII detector operating at the BEPCII collider, a partial wave analysis of the decay $J/ψ\to ϕπ^{0}η$ is performed. We observe for the first time two new structures on the $ϕη$ …

By analyzing $4.48\times10^8$ $\psi(3686)$ events collected with the BESIII detector, we observe the decays $\chi_{cJ} \to n K^0_S\bar\Lambda + c.c.$ ($J=0$, 1, 2) for the first time, via the radiative transition $\psi(3686) \to \gamma \chi_{cJ}$. The branching fractions are determined to be …
