Search for the lepton-family-number nonconserving decay μ -> e + γ
Abstract
The MEGA experiment, which searched for the muon- and electron-number violating decay μ -> e + γ, is described. The spectrometer system, the calibrations, the data taking procedures, the data analysis, and the sensitivity of the experiment are discussed. The most stringent upper limit on the branching ratio of μ -> e + γ) < 1.2 x 10-11 was obtained.
