- Charged Lepton Flavour Violation: An Experimental and Theoretical Introduction (2017, methodology): “Since the main background comes from accidental coincidences, a blind maximum likelihood analysis was adopted [49, 295], meaning that events that are in a window in the (Eγ , teγ) plane too close to the signal are put in a separate data stream which is not accessible by the collaboration.”
