Description
MEG experiment is a rare muon decay search experiment. A muon rare
decay μ + → e + γ violates lepton flavor conservation. The standard model
predicts too small branching ratio to observe, however many new theories
predict observable branching ratio. MEG experiment has sensitivity to the
background ratio better than 10 −13 which is two orders of magnitude
better than current experimental limit 1.2×10 −11. One feature of the
experiment is a liquid xenon scintillation gamma ray detector. The detector
consists of 800 litters of liquid xenon and 850 photo-multipliers. We
performed beam tests to measure resolutions of the detector using
prototype. MEG experiment starts physics data taking in 2007.
