Experimental Nuclear and Subnuclear Physics: MEG
The very current state of the description of all observed elementary particles an their interactions is explained by the Standard Model. The discovery of neutrino oscillations indicates that the Standard Model is incomplete: it led towards a Grand Unified Theory (GUT) which predicts the a broken symmetry of the flavour quantum number with charged leptons. The experimental observation of the broken simmetry event would be a proof that time is come to overtake the Standard Model. The MEG experiment pursue to observe a muon decay to a photon and an electron or improve the actual experimental limit of two orders of magnitude. The MEG experiment is followed by an international collaboration using the proton accelerator at the Paul Scherrer Institute (PSI), Switzerland. The Italian side of the MEG collaboration is financed by the Instituto Nazionale di Fisica Nucleare (INFN). The Pavia group is involved with design, electronics and software of the timing counters (TC) detectors.
