First Observation of the Decays chi_{cJ} -> pi^0 pi^0 pi^0 pi^0

BESIII Collaboration

We present a study of the P-wave spin -triplet charmonium chi_{cJ} decays (J=0,1,2) into pi^0 pi^0 pi^0 pi^0. The analysis is based on 106 million \psiprime decays recorded with th…

Evidence for psi' decays into gamma pi^0 and gamma eta

The BESIII Collaboration

The decays psi'->gamma pi^0, gamma eta and gamma eta' are studied using data collected with the BESIII detector at the BEPCII e^+e^- collider. Processes psi'->gamma pi^0 and psi'->…

Measurements of h_c(^1P_1) in psi' Decays

The BESIII Collaboration

We present measurements of the charmonium state $h_{c} (^{1} P_{1})$ made with 106M $ψ^{'}$ events collected by BESIII at BEPCII. Clear signals are observed for $ψ^{'} \to π^{0} h_{c}$ with and withou…
