Description
The MEG Experiment searches for a lepton flavour violating muon decay, μ+ → e+γ, with a branching ratio sensitivity of 10-13 in order to explore the parameter region predicted by many theoretical models beyond the Standard Model. The first physics run has been performed in 2008, and the second phase of data taking was carried out in 2009 after some detector upgrades. We have performed a likelihood analysis with a sensitivity of 6.1 x10-12, which is approximately twice better than the current upper limit set by the previous experiment, and set an upper limit on the branching ratio B(μ+→e+γ)<1.5x10-11(90%C.L.).
