Experimental tests of lepton universality in tau decay

The branching fractions for τ→eνντ, μνντ, and hντ are measured using data collected with the CLEO detector at the CESR e+e- collider: Be=0.1776±0.0006±0.0017, Bμ=0.1737±0.0008±0.0018, and Bh=0.1152±0.0005±0.0012, where the first error is statistical, the second systematic, and h refers to either a c...
