Measurement of the +e+ branching ratio

Academic Article

Abstract

  • A measurement of the +e+ branching ratio gives Re=(e+e)(+)=1.2265 ± 0.0034(stat) 0.0044(sys) ×10-4. This result is in agreement with standard model calculations and confirms the hypothesis of electron-muon universality at the 0.2% level. © 1994 The American Physical Society.
