Description

The search for charged lepton flavor violation in muon decays is one of the most prominent probes for new physics, with unobservable rates predicted by the Standard Model and an almost unavoidable enhancement in its extensions, up to the sensitivity of the current experiments. The MEG II experiment at PSI searches for the $\mu \to e \gamma$ decay, with a projected sensitivity down to $6 \times 10^{-14}$ on the branching ratio, an improvement of one order of magnitude with respect to the previous experiment, MEG. In 2025, the MEG II collaboration published a search for $\mu \to e \gamma$ on a sample of data corresponding to $\sim 25\%$ of the expected final statistics. An upper limit of $BR(\mu \to e \gamma) < 1.5 \times 10^{-13}$ at $90\%$ C.L. was obtained, which improves the MEG limit by a factor of nearly 3. We will present the current status of the experiment, the latest results on the $\mu \to e \gamma$ search and the status and prospects of searches for other muon exotic decays with the MEG-II detector.
