Description
τ lepton is a fundamental particle in the standard model, and its mass is a very sensitive quantity in testing the lepton-universality.
BESIII gave the most precise τ mass value in a single measurement in 2014, but the accuracy is still much lower than those of electron and muon.
In order to improve the accuracy of τ mass measurement, more than 130 pb-1 τ mass scan data were collected in April 2018, and the uncertainty of mτis expected to be reduced as the level of 100 keV.
