The branching fractions for !ee, , and hh are measured using data collected with the, where the rst errors are statistical, the second systematic, and h refers either to a charged or K. Also measured is the tau mass, m=(1778.21.4) MeV. Lepton universality is aarmed by the resulting relative branching fractions (B/Be=0.97770.00630.0087, B h /Be=0.64840.00410… (More)
