Phys. Rev. Lett. 83, 1521–1524 (1999)New Limit for the Lepton-Family-Number Nonconserving Decay μ+→e+γReceived 10 May 1999; published in the issue dated 23 August 1999 An experiment has been performed to search for the muon- and electron-number nonconserving decay μ+→e+γ. The upper limit for the branching ratio is found to be Γ(μ+→e+γ)/ Γ(μ+→e+νν̅ )<1.2×10-11 with 90% confidence. © 1999 The American Physical Society URL:
