Abstract
We measure the mass of the tau to be 1775.1 +/- 1.6(m(cn)(stat.)) +/- 1.0(m (cn)(sys.)) MeV using tau from Z(0) decays. To test CPT invariance we compa re the masses of the positively and negatively charged tau. The relative ma ss difference is found to be smaller than 3.0 x 10(-3) at the 90%. confiden ce level.
