first tau-neutrino “appearing” out of several billion of billions muon neutrinos

Layout of the CNGS beam line.
The OPERA neutrino experiment [1] at the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in direct appearance mode in the νμ→ντ channel, the signature being the identification of the τ− lepton created by its charged current (CC) interaction [2]. See: Measurement of the neutrino velocity with the OPERA detector in the CNGS beam-

Computer reconstruction of the tau candidate event detected in the OPERA
experiment. The light blue track is the one likely induced by the decay of a tau lepton
produced by a tau-neutrino. See: The OPERA experiment
