Popis: The MEG experiment took data at the Paul Scherrer Institute in the years 2009--2013 to test the violation of the lepton flavour conservation law, which originates from an accidental symmetry that the Standard Model of elementary particle physics has, and published the most stringent limit on the charged lepton flavour violating decay $��^+ \rightarrow {\rm e}^+ ��$: BR($��^+ \rightarrow {\rm e}^+ ��$) $
