Abstract

We measure the mass of the τ to be 1775.1 ± 1.6(m(cn/stat.)) ± 1.0(m(cn/sys.)) MeV using τ from Z⁰ decays. To test CPT invariance we compare the masses of the positively and negatively charged τ. The relative mass difference is found to be smaller than 3.0 × 10^-3 at the 90% confidence level.
