Detected neutrino candidate in the FASER detector - In the rear part a muon can be seen (red line), which was produced by a neutrino in the tungsten/emulsion detector (yellow). Secondary particles are also produced (protons, electrons, positrons, photons), which are detected in the interface tracker (yellow lines).
