- Abstract
- The mass of the tau lepton has been measured in the decay mode tau -> 3 pi nu(tau) using a pseudomass technique. The result obtained from 414 fb(-1) of data collected with the Belle detector is M-tau=[1776.61 +/- 0.13(stat)+/- 0.35(sys)] MeV/c(2). The upper limit on the relative mass difference between positive and negative tau leptons is |M-tau(+)-M-tau(-)|/M-tau < 2.8x10(-4) at 90% confidence level.
