Measurement of the branching ratio

Academic Article


  • A new measurement of the branching ratio gives R =[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. © 1992 The American Physical Society.
