Status and perspectives of the MEG experiment
We present the status and the perspectives of the MEG experiment which has been searching for the Lepton Flavour Violating decay μ+ → e+γ for several years. In a dataset corresponding to 3.6 × 1014 positive muons stopped on target we didn’t find any evidence for this decay and established an upper b...

In a dataset corresponding to 3.6 × 1014 positive muons stopped on target we didn’t find any evidence for this decay and established an upper bound on the μ+ → e+γ branching ratio of 5.7 × 10−13 at 90% C.L., with a sensitivity of 7.7 × 10−13, which improves our world best limit by a factor of 4 and the best previous limit by a factor of 20.
