| Abstract | A measurement of the number of J/Ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/Ψ. The number of J/Ψ events taken in 2009 is recalculated to be (223:7 ± 1:4) ×10~6, which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the BESIII software. The number of J/Ψ events taken in 2012 is determined to be (1086:9 ±6:0)×10~6. In total, the number of J/Ψ events collected with the BESIII detector is measured to be (1310:6±7:0)×10~6, where the uncertainty is dominated by systematic e ects and the statistical uncertainty is negligible. |
