The field of Lepton Flavor Violation is fascinating for search of new
physics beyond Standard Model. The MEG experiment is starting to
investigate the decay of a muon into a positron and gamma, without
emission of neutrinos and thus violating Lepton Flavor: such a process
is strictly forbidden by the SM also in the framework of neutrino
oscillations, giving a precise probe to shed light on the various
theories proposed to extend SM. A comprehensive look on the experimental
technique is given, and since the data taking is under way, the most
recent news will be available.
