Observation of eta(c) -> omega omega in J/psi -> gamma omega omega
(AMER PHYSICAL SOC, 2019)Using a sample of (1310.6 +/- 7.0) x 10(6) J/psi events recorded with the Beijing Spectrometer III detector at the Beijing Electron Positron Collider II, we report the observation of the decay of the (1(1)S(0)) charmonium ... -
Observation of ψ(3770) → ηJ/ψ
(American Physical Society, 2023)Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, the Born cross section of the process e+e- -> eta J=psi at a center-of-mass energy pffisffi = 3.773 GeV is measured to be (8.88 ...
