A measurement of the tau mass and the first CPT test with tau leptons
G. Abbiendi, the OPAL collaboration
Abstract
We measure the mass of the tau lepton to be 1775.1+-1.6(stat)+-1.0(syst.) MeV using tau pairs from Z0 decays. To test CPT invariance we compare the masses of the positively and negatively charged tau leptons. The relative mass difference is found to be smaller than 3.0 10-3 at the 90% confidence level.
