“…The trigger efficiencies for BESIII data were studied in 2010 [13] and 2021 [14]. The trigger efficiency for the (type-II and type-III) events is found to be close to 100.0%, while it is 98.7% for the type-I events [13]. Since the fraction of the type-I events is only about 3% of the total selected hadronic events, the associated systematic uncertainty is negligible.…”

The number of $\psi(3686)$ events collected by the BESIII detector during the 2021 run period is determined to be $(2259.3\pm 11.1)\times 10^6$ by counting inclusive $\psi(3686)$ hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of $\psi(3686)$ events collected during the 2009 and 2012 run periods are updated to be $(107.7\pm0.6)\times 10^6$ and $(345.4\pm 2.6)\times 10^6$, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of $\psi(3686)$ events in the three data samples is $(2712.4\pm14.3)\times10^6$.

“…The remaining processes excluding η → γπ + π − are simulated using a phasespace (PHSP) generator. Based on studies of Bhabha, di-muon and inclusive hadronic event samples, the trigger efficiency for events with charged tracks is found to be approximately 100% [32,33] and is thus neglected in this analysis.…”

Using a sample of (10.09 ± 0.04) × 10 9 J/ψ events collected with the BESIII detector, a partial wave analysis of J/ψ → γη η is performed. The masses and widths of the observed resonances and their branching fractions are reported. The main contribution is from J/ψ → γf0(2020) with f0(2020) → η η , which is found with a significance of greater than 25σ. The product branching fraction B (J/ψ → γf0(2020))•B (f0(2020) → η η ) is measured to be (2.63±0.06(stat.) +0.31 −0.46 (syst.))× 10 −4 .
