Abstract
Charged-lepton-flavour–violating decays are prohibited in the framework of the Standard Model of elementary particles, but many of its extensions predict measurable values for such decays. Several experiments are running or being designed to measure (or to set a limit on) such processes. Among these, the MEG experiment has recently set a new upper limit on the μ → eγ branching ratio B < 5.7 × 10 −13 at 90% CL. The process has a simple kinematics but very good resolutions are needed for discarding the huge background. In order to improve its sensitivity, an upgrade of the experiment is under development, and will start taking data in 2016. The foreseen sensitivity of the upgraded apparatus will be about 5 × 10−14 on the branching ratio of the process.
