36 Lepton Flavor Violation When a muon stops in matter, the principal interactions are: Capture on Nucleus: µ - N(Z,A) ν µ N(Z-1,A) Decay in Orbit: µ - ν µ e - ν e (DIO) Coherent conversion is µ - N(Z,A) e - N(Z,A), and the signal is a monoenergetic electron beyond the DIO endpoint. The MECO experiment at BNL will measure: R µe = Γ[µ - N(Z,A) e - N(Z,A)]/ Γ[µ - N(Z,A) ν µ N(Z-1,A)] A single event implies R µe > 2 X

40 Summary An extraordinary amount has been learnt about electroweak physics in the past fifty years Further progress requires a coherent effort across High Energy Physics, Nuclear Physics and Particle Astrophysics Accelerator- and non-accelerator experiments will play equally important roles Together, we will finally address some of the outstanding questions unanswered by the current version of the electroweak theory Your generation can help towards generating the required unity and coherence
