“…The selection criteria for charged tracks, photons, K 0 S , and π 0 are the same as those reported in Ref. [13]. The η ð0Þ candidate is required to have an invariant mass of the γγðπ þ π − ηÞ combination in the interval ½0.490; 0.580ð½0.938; 0.978Þ GeV=c 2 .…”

“…The possible bias due to the measurement method is estimated to be 0.2% by comparing the measured BF in the GMC sample, using the same method as in data analysis, to the value assumed in the generation. The uncertainties from particle identification and tracking efficiencies are assigned to be 0.5% and 1.0% [13], respectively. The relative uncertainty in the π 0 reconstruction efficiency is 2.0% [13], and the uncertainty in η reconstruction is assumed to be comparable to that on π 0 reconstruction and correlated with it.…”
