Search for the lepton flavour violating decay μ+→e+γ with the full dataset of the MEG experiment MEG Collaboration
The final results of the search for the lepton flavour violating decay μ + → e + γ based on the full dataset collected by the MEG experiment at the Paul Scherrer Institut in the period 2009–2013 and totalling 7.5 × 10 14 stopped muons on target are presented.
