Within the Standard Model (SM), in spite of neutrino oscillations, the flavor of charged leptons is conserved at very good approximation, and therefore charged Lepton Flavor Violation (cLFV) is expected to be unobservable. On the other hand, most New Physics models predict cLFV at a level within the experimental reach, and processes like the mu to e gamma decay became a standard probe for physics beyond the SM. The MEG experiment, at the Paul Scherrer Institute (Switzerland), searches for this decay, down to a Branching Ration of a few $10^{-13}$, exploiting the most intense con! tinuous muon beam in the word. In this seminar, I will present the recent results from MEG, and the plan for an upgrade of the experiment, aiming at an improvement of the sensitivity by one order of magnitude within this decade.
