“…, which are listed in Table 4, with 10 10 J/ψ event sample and 10 12 J/ψ event sample, respectively. Here, we also note that the detection efficiency ε K 0 L is at the level of 10 −3 at BESIII [43,60], so the K 0 S − K 0 L asymmetry can be observed in the decays with…”

“…and J=ψ →D 0K0 [4] and set upper limits on the order of 10 −4 ∼ 10 −5 using a sample of 5.8 × 10 7 J=ψ events [5,6]. With the prospect of high-statistics J=ψ samples, theoretical calculations of the branching fractions of two-body hadronic weak decays of J=ψ → DP=DV, where D represents a charmed meson and P and V the pseudoscalar and vector mesons, respectively, have been performed [7][8][9][10][11][12].…”
